Just a quick technical question.
When a planet is stationary, how long do you count it as stationary? Just right on that day, +/- a few hours or +/- a day?

My guess would be that the whole time the planet is within the stationary degree, it can be considered stationary. The faster moving planets will not take very long to move out of that degree, but the slower moving planets might take a few days or even possibly weeks to move from the stationary degree... this is why I am asking.

I don't have a single criterion for all planets, but the bottom line I start with is when it hasn't moved 0°01. Thus, the Mars station at 3°37' Capricorn is stationary as long as its longitude is 3°37' Capricorn (which ends up being three or four days; with Pluto it could be a couple of weeks).

The main exception is Mercury, and sometimes Venus, which kick into gear too fast and the above definition could last only a few hours. I give them minimum of one day. (Perhaps that seems the case because most astrological effects tend to organize themselves into one-day categories, erhaps bounded by sleep cycles.)
