theres this hadeeth which says even if a woman doesnt have to pray( their off days) they should visit the mosque atleast
i am not sure but i have heard that eid ke namaz is like the pay day.We fast through out a month and on eid God blesses us suwaab n stuff? not sure though.

well, what i learned from my dad i just passed it on to others. its more common in the west than in the east. Hazrat Omar [r.a.] had put a ban on women's visit to masaajid and there is a Hadees that if there were supposed to eb another prophet it wud have been Omar [r.a.].**
