General wondering about wedding charts

Can you study the chart date and time you got married, in the same way you would a birth chart?

I would expect so. It would be exactly as if you were deciphering an election ahead of time. I don't know if Dr Farr used election before he got married but several times he referred back to his wedding chart to give me examples when he was helping me learn

I have taken a look at mine, and most of it just seems to exemplify the events of that day - Lots of plants in Sagi - marriage abroad etc.
I am not sure if it actually predicts how that marriage will pan out?
Would you look to rulership? I.e Aries rising, Mars was in Capricorn that day, which dictates the general theme?

The Tenth house and its lord shows things that happen in the marriage and its overall "health" or public appearance. The fourth and its lord shows how the marriage ends.
