My wedding day is on Friday.. is there any problem based on astrology...

This Pagan says no ! As it is associated with the planet Venus and the Norse goddess Frigg, "the patron of marriage and motherhood, and the goddess of love and fertility" according to Encyclopedia Mythica:

- I'd say it was a supremely suitable day on which to wed. The Goddess Guide also says "Frigg was the Norse Goddess of marriage, childbirth, motherhood, wisdom, household management and weaving and spinning" here:

So it would seem you have nothing to fear from Friday !
