In my family, there are basically two gift-giving periods.
My parents birthdays are on Dec. 20 and Jan. 6 only broken up by Christmas in the middle (so I get my brothers gifts). In the summer, my birthday, another brother, and my younger brother's birthdays are May 30, 30, and 31 respectively. On either side of that is Mother's Day and Father's Day.
Basically, I've never viewed really viewed my birthday or Christmas as anything other than a time to get others gifts.
