Now, as I see astro.com has the option for tertiary progressions.
For example my tertiary progressions for the current month look like this:

Astro.com uses my natal birthtime for calculating the angles,w hich seems to be right, as it is MY birthtime, and I am interested in MY progressions and not someone else`s born on that day.

However, this chart is valid for a whole month, but of course the planets move along, over the course of a day. For most planets that is not interesting.

But what about the Moon and the angles?

The progression chart astro.com gives apparently is calcculated for the FIRST day of that month and used for all following days for the month as well.

But now look at my tp for next month:


As you can see the Moon moves about 12-13 degrees a day, so if I am interested in a very specific date; let`s say 12th august, wouldnīt I need to calculate how many degrees the Moon moved on since the first day of that month the tertiary is valid for?

The first day of the month might relate to my original birthtime, but the day (we use for tertiary progressions) has 24 hours, so wouldnīt we need to adjust that?

let`s stick with the 12th august in my example.

the month the tertiaries are valid for has 28 days;
the day, the tertiaries usse to calculate, has 24 hours.

So the first day of the month relates to my birthtime, but for every following day we need to add about 51 minutes to the time (24 hours = 1440 minutes divided by 28 days).

The 12th august is 10 days into the month, so translating that to the time it relates to 8 and a half hour, which I would have to add to the original time.

So really the EXACT specific data for my tertiary progression for 12th august would be 4th may 1976, but 14:37 UT, which of course would give a totally different set of angles.

Jeez, totally complicated.

But this would give a Moon of 12-13 Cancer (which means my calculation is right - see first post),

but totally different angles!

ASC would be on 28 Virgo with MC on 28 Gemini.

This would be the exact set of angles for the beginning of the day of 12th august, but if that event happened at 7 p.m., the angles actually would already be further.

Why?
Because if the angles move appr. 51 minutes per day, it means they move about 2 minutes per hour that day. (approximately).

So let`s say the event was at 7 p.m., that would be 19 hours into the day. Since we have to add 2 minutes per each hour that day, we would need to add about 38 minutes to the already found 14:37 UT (or 2:37 p.m. UT). Which would give us a time of 3:15 p.m. UT) and that would place the ASC already in Libra!

so, keeping that in mind if we want to work with tertiary progressions astro.com sseems to be just the starting point for a LOT of work.

what a difference a day make, hu?

BTW it places the TP ASC on my natal MC with an orb of only 36 minutes, with Pluto in the 1st house and that bunch of planets in the 8th house.
And TP IC conjuncts my natal Venus by 1°05.

Boy does THAT make sense! lol

But the thing I want to highlight is, if we simply use the tertiary as given by astro com, for every day of the month, we will always get totally wrong angles and houseplacements (except for the first day of that month) and also incorrect Moon-aspects.

The downside is, if we want to use these, we probably have to adjust it manually

1. Pick the date astro.com gives for the tertiary progression of any given month.

2. Adjust the birthtime:
a)add 51 minutes for every day that has passed since the first day of that month (as astrocom states: in my case the first day of the month was 3rd august, and counting from there, including the 3rd august, means the 12th august was day number 10 in that month)
b) add 2 more minutes for every hour that has passed since the midnight of that day,w hich is the beginning of any day

add these to your original birthtime, and use that newfound time .

Why is that so btw?

But I have to look into more to be certain.

I think though that you can simply use the chart given by astrocom. as really only Sun and Venus and Mercury might move a degree within a month, BUT you have to adjust the Moon. That is all calculating it really needs.

And then I would look for tight, one degree, aspects within the chart and especially to natal.

I have rather randomly picked some occasions I had encounters with a guy (always the same) that made an impression on me. And everytime my natal Moon was being triggered.

1.
TP Venus conjunct natal Moon exact

2.
TP Moon trine natal Moon exact

3.
TP ASC square natal Moon exact

4.
TP Moon conjunct natal Moon (though with a 2 degree orb)

TP Venus was sextile natal Moon precise (0.00 orb) though

5.
no triggering of natal Moon

but TP Moon was conjunct my natal IC exact

and the nodal axis was on the antiscion of natal Moon

TP ASC was widely trine natal Moon (2 degrees)

6.
TP MC conjunct natal Moon exact

You said the first day of the month for you was Aug 3. Why is the first day not Aug 1?
