Be sure to tell why!

Though I learnt using Equal House.

I don't really have a reason. But it seems to make more sense to have the 10th lead by the M.C, and unequal houses when the seasons are unequal.

But the Placidus is over used, and some astrologers prefer the Koch system, for example Stephen Arroyo...

I am torn between Koch and Equal at the moment. Equal changed my whole chart: Put Pluto in my 5th along with Mercury, and I lost my 6th house stellium, but I'm not really crying about it.
It moved my Saturn from the 3rd to the 2nd house, which might actually explain a lot financially since Mercury rules my 2nd and Saturn squares it - I always had a problem with money in the past, it was a major problem which felt really exaggerated. It makes more sense with Saturn in there, but I'm still not so sure.

My NN moved from the 9th to the 8th, and I don't know how I feel about that either.
My Jupiter is in the 9th instead of the 10th by Equal system which makes a LOT of sense because I seem to feel enormously lucky and expansive in regards to travel.

Koch houses are calculated this way:

1. You take the degree of the midheaven at a certain time.

2. Then you go backwards in time, until the degree of the midheaven (at the time of your birth) becomes the ASC.

3. You cut the time into three parts, which give you the housecusps of 11th and 12th house.

This means that the housecusps 11 and 10th relate actually to a time BEFORE your birth.

Example:

My MC is on 05° Libra.

5° Libra is on the ASC at about 1 a.m. on my birthday. But that is 6 hours BEFORE my birth.

Now I would cut these 6 hours into 3 parts and calculate the ASC. So in my case the ASC for 3 a.m. would give me the housecusp of the 11th house.

But the thing is if we assume that the ASC is the exact moment we come into life, which separates Non-existence from Existence, then the ASC is also the beginning of the circle of houses. The exact degree of the rising, not a few hours before that or after that.

Placidus does a similiar calculation, but he starts from the rising degree and counts to the MC and then divides the time into three parts. We still can argue if that is okay, but at least in the Placidus system the ASC is really the rising degree and beginning at the moment of one`s birth.
