Progressed
Aspects of
Standard
Astrology
To one who has learned to erect a birth-chart in which the de-
gree and minute of the zodiacal sign occupied by each of the
faster moving planets is ascertained through the use of loga-
rithms, calculating progressed aspects by the use of logarithms
should be unusually easy; for there are only five additional
simple processes to remember, one of which relates exclusively
to calculating minor progressed aspects. Thus calculating ma-
jor progressed aspects resolves itself into four easy steps; and
calculating minor progressed aspects resolves itself into par-
allel easy steps, but with the fourth one split into two easy
steps to facilitate handling the rather clumsy minor progres-
sion time ratio.
For major progressed aspects the four easy steps follow
each other in this order:
I. Find the Limiting Date. This is done but once for each
birth-chart.
II. Find the Major Progression Date. This must be done
for each calendar year during which progressed aspects
are calculated.
III. Find the EGMT Interval When the Aspect is Perfect.
This must be done for each progressed aspect calculated.
IV. From the EGMT Interval, Find the Calendar Date When
the Aspect is Perfect. This must be done for each pro-
gressed aspect calculated.
Now before explaining, and giving examples, of each of these
four distinct and necessary steps, let us examine the four simple
processes involved that are new in the sense that they are not
used in the original erection of the birth-chart. Two of these
relate to bases, or starting points.
I think anyone will recognize that in making any calcula-
tion if the base, or starting point, is erroneous, the result ob-
tained will also be erroneous, no matter how accurately the
computation otherwise is made. And in major progressed as-
pects we have two bases, or starting points; one, the Limiting

Date (L.D.), from which we always must start to compute the month
and day of month within the given calendar year when the aspect is
perfect; and the other, the Major Progression Date (Map.D.), from which
it always is necessary to start to ascertain the calendar year during which
the aspect is perfect.
I have been correcting examination papers embracing progressed
aspects for more than a quarter of a century; and I have found that when
errors appear in the timing of major progressed aspects, in more than
9% of the cases it is because the student has used an erroneous Limiting
Date, and in more than 25% of the cases it is because he has used an
erroneous Major Progression Date. And these errors appear in that pro-
portion whether the progressed aspects are calculated by proportion or
by logarithms; for however calculated if the starting point is wrong, the
result will not be correct.
The third new thing that must be remembered is that when loga-
rithms are used in calculating progressed aspects the process is just the
reverse of that when they are used to ascertain the position of a planet
in the birth-chart. That is, instead of adding the logarithms, the loga-
rithm showing the smaller number is subtracted from the logarithm
showing the larger number.
Major Progression Time-Velocity Ratio
The fourth new thing is that any calendar time interval can be converted
into a major progression time interval, and any major progression time
interval can be converted into a calendar time interval, at the ratio of 4
minutes major progression time being equal to day calendar time, and 2
hours major progression time being equal to 1 month calendar time. As
we must use this ratio between the time-velocity level of major progres-
sion time and the time-velocity level of calendar time to establish the con-
venient and correct point of contact which is called the Limiting Date,
and that other convenient and correct point of contact called the Major
Progression Date, let us observe it more in detail, bearing in mind that
progression time is identical with the time of the ephemeris positions.
24 hours (one day) major progression time equal 12 months (one
year, or 365¼ days) calendar time.
2 hours (120 minutes) major progression time equal 2/24 years (one
month, or 30 days) calendar time.
4 minutes (120 divided by 30) major progression time equal 1/30
month (one day) calendar time.
Step 1. Finding the Limiting Date
In erecting any chart of birth the correct positions of the planets in the
chart are found by moving them ahead, or moving them back, from
their positions in the ephemeris their amount of travel during a certain
Equivalent Greenwich Mean Time Interval. If this EGMT Interval is af-

ter noon it is called a plus interval; if before noon, it is called a minus
interval.
Now if the EGMT Interval is after noon, the distance the planets
travel during this plus interval must be added to their noon positions.
And if, instead of starting with the noon positions, we start with their
positions in the chart of birth and want to move them back to the noon
position in the ephemeris, we must subtract their amount of travel dur-
ing this same EGMT Interval.
But if the EGMT Interval is before noon, to place them in the chart
their amount of travel during the minus Interval must be subtracted
from noon. Then, if we start with their birth-chart positions and want to
move them again to their ephemeris noon positions, we must add their
travel during the same interval.
Mark this: if we add their travel to put them in the birth-chart, we
must subtract their travel to get them back to their noon positions; and
if we subtract their travel to put them in the birth- chart we must add
their travel to get them back to their noon positions. In other words, to
get them back to noon positions as they are in the ephemeris, we use
their travel during the same interval, but employ the opposite algebraic
sign.
Yet whether we move them back, or move them ahead, we use an
EGMT Interval, which being ephemeris time is also major progression
time. And any interval of major progression time, as has previously
been explained, can be converted into calendar time by calling each 2
hours a month, and each 4 minutes a day. Thus are we in a position
readily to ascertain just what date of calendar time is represented by
the noon positions of the planets on any day, including the day of birth.
And mathematically it makes no difference whether the calendar date
so ascertained was before birth, after birth, or after death; for we are not
here considering an event in any person's life. We are considering time;
and it is assumed that there was calendar time before any particular
individual was born, and that there will still be calendar time after he
has passed beyond the tomb.
Now it is true that an Interval on the day before birth, or an Inter-
val on the day after birth, is sometimes used in actually placing the plan-
ets in a birth-chart. But if we are to start with the day of birth, and thus
have a standardized, and therefore easy to remember, point of contact
between major progression time and calendar time, we must always
use the EGMT Interval on the day of birth. I have been correcting ex-
aminations on natal astrology over a quarter of a century; and I find
that by far the most common mistake of students is to try to use an
Interval on some other day, and thus not get the correct Limiting Date.
Even should the EGMT Interval be 18 hours, or 28 hours, as it some-
times is when the zero (midnight) ephemeris is used, always use the
interval on the day of birth; and always calculate the Major Progression
Date from the day of birth.
No confusion will arise when the zero (midnight) ephemeris is
employed; for the rule still is to convert the EGMT Interval, which was

used to calculate the birth-chart places of the planets, into calendar time.
The Limiting Date will be six months earlier than if a noon ephemeris
had been used; but as the ephemeris positions of the planets are twelve
hours earlier also, the calendar time of all progressed aspects will be
exactly the same.
Whichever ephemeris is used, to get the Limiting Date, convert the
EGMT Interval into months and days of calendar Interval, and chang-
ing the algebraic sign used when the planets were placed in the chart,
add or subtract the Interval so found to or from the date of birth. This
may take the Limiting Date back into the year previous to birth, keep it
in the year of birth, or move it ahead into the year following birth. Into
whatever year it takes it, the YEAR is an essential part of the Limiting
Date. If this year is not the year of birth, and the year of birth is used as
a base for calculating the progressed aspects, they will all be wrong.
We find the Limiting Date for the Mickey Rooney example chart
thus: The EGMT Interval for which the planets were placed in the birth-
chart is plus 4h. Dividing 4 by 2 gives 2 months. The calender time in-
terval is therefore 2 months. Changing the algebraic sign from plus to
minus we must subtract this from date of birth.

80 minutes. Dividing 80 by 4 gives 20 days. The calendar time interval is
therefore 2 months, 20 days. Changing the algebraic sign from minus to
plus we must add this to date of birth.

Step II. Finding the Major Progression Date
The Limiting Date is used primarily to determine, within some particu-
lar calendar year, the month and day when each major progressed as-
pect is perfect. But to ascertain within which calendar year the aspect is
perfect requires that we find the Major Progression Date. And for find-
ing it, we use the Limiting Date as the base or starting point in calendar
time, and the day of birth as the base or starting point which is equiva-
lent to it in progression time. Then to find the Major Progression Date,
merely count ahead in the ephemeris from the day of birth (progression
time), as many days as years of life (calendar time) have elapsed since
the Limiting Date. 25% of all the errors of our students of progressed
aspects during a quarter of a century have arisen from counting ahead
in the ephemeris from the date of birth as many years as the person is
old, instead of correctly counting ahead as many years as have elapsed
SINCE THE LIMITING DATE.

the Limiting Date as many years as days have elapsed since birth thus:

Step III. Finding the EGMT Interval When the Aspect is Perfect
When you placed the faster moving planets in the chart of birth you
found it convenient to use logarithms to ascertain how far they had
traveled during a given EGMT Interval. To do this you found the loga-
rithm of the EGMT Interval (Constant Log.). To this you added the loga-
rithm of the daily motion of the planet whose position was being calcu-
lated. The sum gave you the logarithm of the distance traveled by the
planet during that EGMT Interval.
Take the Moon in the Mickey Rooney example chart. Here is the
way you calculated it:
Log. (d) .7781 4h 00m plus EGMT Interval
Log. (a) .2915 12° 16` add daily motion
Log. (b) 1.0696
2° 03' travel during EGMT Interval.
Now instead of finding how far the Moon traveled during a given
interval, suppose you wish to know how long an Interval it took the
Moon on September 23, 1920, to move 2° 03'. That is, suppose the Moon
background image
Progressed Aspects of Standard Astrology
25
must travel 2° 03' to make the perfect aspect with some other planet.
How would you go about it to find this interval ? Well, if you add two-
numbers to get their sum, you can always find the other number by
subtracting one of them from this sum. Therefore you would subtract
the logarithm of the Moon's daily motion (a) from the logarithm of 2°
03' (b), and this would give you the logarithm of the Interval (d) thus:
Log. (b) 1.0696
2° 03` distance Moon must travel
Log. (a) .2915 12° 16`
subtract daily motion of Moon
Log. (d) .7781
4h 00m plus EGMT Interval
Such EGMT Intervals, found in exactly this way, are what we seek
in calculating either major or minor progressed aspects. (b) as in this
instance, is always the distance the aspect is from perfect. (a) is always
the gain of the two planets in one ephemeris day (progression time) in
closing the aspect. And the logarithm of (a) is always, as above, sub-
tracted from the logarithm of (b) to get the logarithm of (d) the EGMT
Interval.
1. When the progressed aspect is from a progressing planet, either
direct in motion or retrograde in motion, to a birth-chart planet,
the gain (a) is the daily motion of the progressing planet.
2. When the progressed aspect is between two progressing planets,
if both are direct in motion or if both are retrograde in motion
the gain (a) is the difference between the daily motions of the
two planets.
3. When the progressed aspect is between two progressing planets,
one of which is direct in motion and the other retrograde in mo-
tion, the gain (a) is the sum of their daily motions.
In the eleven examples which follow, the capital letter prefixing
each corresponds to the same capital letter used in Step IV to complete
finding the date the aspect is perfect.
(A) As an example of (1) when the progressing planet is direct in
motion, in the John Edwards chart on April 5, 1920, the Sun reaches 15
Aries 47 and is then semi-square birth-chart Venus.

(D) As an example (2) when both progressing planets are retro-
grade in motion, in the John Edwards chart both Mars and Jupiter are
retrograde and on March 26 in the ephemeris they form the square as-
pect. The daily motion of Jupiter on this day is 1`and the daily motion
of Mars is 9'. The difference in daily motion is 8' which constitutes the
daily gain (a) of the faster planet on the slower. On March 26 the ephem-
eris shows the aspect (b) 4' from perfect.

(E) As an example of (3) when one progressing planet is direct in

retrograde in motion form the trine aspect.

(F) Parallel aspects of course form no exceptions, but are handled in
exactly the same manner. Thus in the Mickey Rooney birth-chart Nep-
tune has declination 16 N 56, and in the ephemeris the Moon reaches this
declination, and is thus parallel birth- chart Neptune, on October 1, 1920.
The daily motion of the Moon by declination on this day is 1° 54`,
and as at noon the Moon is 16 N 51 it has 5`to move to complete the
aspect.

Finding EGMT Interval When
Progressed M.C. and Asc. Make Perfect Aspects
Progressing M.C. and Asc. are no exceptions to the general rules, and
are handled precisely as if they were planets. The M.C. must move by
progression, to keep the time velocity ratio constant, exactly as many
degrees and minutes the progressing Sun moves on the same day. The
Asc. must move by progression the proportional amount indicated by a
table of houses for the latitude of birth that corresponds to the given
movement of the M.C. To find the amount of movement by major pro-
gression of the M.C. and Asc. during any calendar year, first find from
the major progressed position of the Sun on the Limiting Date of the
given calendar year the sign, degree and minute occupied by the M.C.
and Asc. on the Limiting Date that year. Then find from the major pro-
gressed position of the Sun on the Limiting Date of the following calen-
dar year the sign, degree and minute occupied by the M.C. and Asc. on
the Limiting Date of that year. The difference between the positions oc-
cupied by the M.C. on the two successive dates is the amount of daily
travel (yearly travel by major progression) of the M.C. The difference
between the positions occupied by the Asc. on the two successive dates
is the amount of daily travel (yearly travel by major progression) be-
tween the two successive dates.
In the Mickey Rooney example chart if we wish to know the daily
motion of the progressing M.C. and Asc. corresponding to the calendar
year commencing on the Limiting Date July 23, 1941, and ending July
23, 1942, we first find the Map.D. for 1941 and 1942. In the example
work we have already found that the Map.D. for 1942 is October 15,
1920. Therefore the MapD. for 1941 is October 14, 1920.

Now turning to the table of houses for 40:43N we find, as if we
were working it for a birth-chart, what sign, degree and minute is on
the Asc. when 7 Libra 41 is on the M.C. The answer is 16 Sagittarius 56.
This is the progressed Asc. July 23, 1941.
Now as the Sun on October 14 moves 1°, this is the daily motion of
the M.C. for progression purposes on that day. Add this 1 ° to 7 Libra 41
and it gives us 8 Libra 41 as the progressed M.C. on October 15 in the
ephemeris, or calendar date July 23, 1942. Then again turning to the
table of houses for 40:43N, and working it as if we were finding it for a
birth-chart, we find that when 8 Libra 41 is on the M.C. 17 Sagittarius 43
is on the Asc.; and this is the progressed Asc. July 23, 1942.
The difference between the progressed Asc. for July 23, 1941 and
the progressed Asc. for July 23, 1947, is 47' which is the daily motion of
the progressed Asc.

(G) When progressed M.C. reaches 8 Libra 20 it will complete the
trine with birth-chart Moon in 8 Aquarius 20. From 7 Libra 41, where it

(I) In this Mickey Rooney chart the progressed Sun is moving faster
than the progressed Ascendant; and as the Sun at birth is 0 Libra 19 and
the Ascendant is 1 Sagittarius 34, progressed Sun will in due time make
the sextile of progressed Ascendant. September 28, 1920, in the ephem-
eris the Sun is 5 Libra 03; and the M.C. calculated as already indicated is
21 Virgo 54; giving an Ascendant of 5 Sagittarius 02. That is, by the
Map.D. for the calendar date July 23, 1925, progressed Sun has passed
the sextile of progressed Asc. by 1'. Calculated as already indicated, the
daily motion of the Ascendant is 42'.
Now as the Sun is moving 59' and the Ascendant is moving 42' per
day, the gain (a) of the faster on the slower is the difference, or 17'.

In calculating progressed aspects of the M.C. and the Asc. to birth-
chart planets-- but not to progressing planets-- it often is convenient
not to find the daily motion of M.C. and Asc., but merely to find the
sign, degree and minute occupied by the Sun in the ephemeris when
the progressed aspect is perfect, and then find the EGMT Interval on
that day which brings the Sun to that place.
(J) If in the Mickey Rooney chart we wish to know when the pro-
gressed Asc. comes to the trine of birth-chart Neptune, we can proceed
thus:
Turning to the table of houses for 40:43N we look down the col-
umn until we find the Asc. as close to 12 Sagittarius 59, where it must be
to complete the aspect, as possible. This brings us to 12 Sagittarius 37
with a M.C. of 2 Libra 00. The Asc. must move 22' to reach the aspect;

and we want to know what degree is on the M.C. when it does reach it.
We note in the table of houses that while the M.C. moves 60'the Ascen-
dant moves 42'. We then solve the proportion 42' : 22': : 60': ?
The answer is 31', which we add to 2 Libra 00 and get 2 Libra 31 as
the M.C. when 12 Sagittarius 59 is on the Asc.

The Easy Way To Calculate Major Progressed Aspects
Step IV. Finding, From the EGMT Interval,
the Calendar Date When the Aspect is Perfect
To find the calendar date when the progressed aspect is perfect, convert
the EGMT Interval, which is progression time, into its equivalent inter-
val of calendar time at the ratio of each 2 hours progression time being
equal to 1 month calendar time, and each 4 minutes progression time
being equal to 1 day calendar time. Then if the EGMT Interval was mi-
nus (before noon) subtract the calendar interval so found from the month
and day of the Limiting Date in the calendar year corresponding to the
Major Progression Date. But if the EGMT Interval was plus (after noon)
add the calendar interval so found to the month and day of the Limiting
Date in the calendar year corresponding to the Major Progession Date.
Using this Major progression time-velocity ratio, let us now in the
order of their sequence, convert each EGMT Interval already found in
the example work into calendar interval, and ascertain the exact calen-
dar date when each such aspect is perfect. As in the eleven examples,
we follow through from step III with step IV, the same capital letter is
employed in both of these steps to indicate the work in calculating the
same major progressed aspect.
(A) In the John Edwards chart we found that April 5, 1920, was
Map.D. for calendar year 1937, and on that day the Sun reached 15 Ar-
ies 47 in semi-square to birth-chart Venus in plus EGMT Interval 9h
21m. We divide the 9 by 2 and it gives 4 mo. with a remainder of 60
minutes. Adding the 60 minutes to the 21 minutes gives 81 minutes.
Dividing 81 by 4 gives 20 days. We thus have 4 months, 20 days to add
to the Limiting Date in 1937.

gives 2 months with a remainder of 60 minutes. Adding the 60 minutes
to the 39 minutes gives 99 minutes. Dividing 99 by 4 gives 25 days.

Finding the Major Progressed Positions of
Planets, M.C. and Ascendant For Any Calendar Date
Under the first subheading of this chapter-- Major Progression Time-Ve-
locity ratio-- it was pointed out that any calendar time interval can be
converted into a major progression time interval, and any major progres-
sion time interval can be converted into a calendar time interval. In Step
II an example was given of converting, in the Mickey Rooney chart, the
calendar year 1942 into the Major Progression Date. It was found that
calendar year 1942 was Major Progression Date October 15 in the ephem-
eris.And by proceeding in the manner there indicated the Major Progres-
sion Date, which is a date showing the ephemeris positions which are
also the major progressed positions of the planets for the Limiting Date
within that calendar year, may easily be found for any calendar year.
In the various examples given under Step IV, we have been starting
with the EGMT Interval on the Map.D. and finding the corresponding
calendar date. To do this we divided the hours by 2, and the minutes by
4, calling the result months and days to add to or subtract from the

Limiting Date. Having found such a calendar date, if we wish to move
back to find the progressed positions of the planets for the correspond-
ing EGMT Interval on the Map.D., we merely have to reverse the calcu-
lations already made. That is, we would convert the Calendar Interval
from the Limiting Date into EGMT Interval by multiplying the months
by 2 and calling the result hours, and the day by 4 and calling the result
minutes. Then if the Calendar Interval were plus (after the L.D.) the
EGMT Interval on the Map.D. would be plus; and if the Calendar Inter-
val were minus (before the L.D.) the EGMT Interval on the Map.D. would
be minus. Having found the EGMT Interval on the Map.D. we would
then calculate the positions of the planets for that plus or minus EGMT
Interval just as if we were placing them in a birth-chart for that ephem-
eris day.
The progressed positions of the planets can be found for any calen-
dar date thus by first finding the Map.D. of the calendar year, then con-
verting the Calendar Interval from the L.D. in that calendar year into
EGMT Interval by multiplying the months by 2 and calling the result
hours, and the days by 4 and calling the result minutes, and on the
Map.D. calculating the places of the planets for the EGMT Interval so
found as if calculating their positions for a birth-chart. This means, of
course, that instead of subtracting the logarithms, the logarithms are
added.
After the progressed position of the Sun has thus been found, add
the signs, degrees and minutes it has moved since birth to the birth-
chart M.C. This gives the correct progressed M.C. From this progressed
M.C., using a table of houses for the latitude of birth, then calculate the
sign, degree and minute that must be on the Asc. This gives the correct
progressed Asc.
