You have asked three major independent questions. I will answer the one relating to timing of your marriage. My other colleagues on this forum may help you with the remaining.
Rahu and Saturn are the planets that may cause your marriage. You should be married in the major-period and sub-period of Mercury that runs between June/2020 and Nov/2022.
The period from 28/November/2020 to 16/Dec/2020 seems very good for this purpose.
yes your lagna is sagg with tob of 2.10 pm and if tob is changed to 2.20 pm lagna changes to capricorn ,and my reading is with capricorn and also sagg .
Thank you very much for your analysis. Really appreciate it.
Sorry, I really don't want to ask too many questions, just one more related one - and also based on the time-frame you had mentioned - does the conjunction of the 5th and 7th lord show spouse of choice/ love in my chart? Moreover if the marriage happens, would it be with all of family's wishes?
The fifth house represents love and the seventh marriage. When the two are related there will be an element of love in marriage. The question remains whether love will be before or after marriage. A love marriage is one that arises out of love. Marriage follows love. This is shown by the relations between the two houses. A marriage having loving relationship between the partners is also shown by this house relationship. In this love follows marriage. How to distinguish between the two. One has to go deeper into this. The analysis is a little complicated but the distinction can be made.
