I also want to know about muhurat for marriage .As per my basic knowledge ,at the time of marriage, the strength of Sun, Moon and Jupiter is analysed in the kundalis of the bride and groom .This is done by calculating the position of these planets in the sign in which they are at the time of marriage from the birth sign.
if Sun is in the fourth, eighth or twelfth sign from the birth sign at the time of marriage, the period is said to be inauspicious. Marriage should be delayed or postponed in such a situation.
I know only brief about it .
