- August 31 → February 28/29 (half birthday - adjusted for February's length)
Frequently Asked Questions About Half Birthdays
How is a half birthday calculated?
A half birthday is calculated by adding exactly 6 months to your birth month and keeping the same day. For example, if your birthday is March 10th, your half birthday is September 10th. If your birthday is August 31st, your half birthday would be February 28th (or 29th in leap years) since February 31st doesn't exist.
What if my half birthday falls on February 29th?
In non-leap years, if your calculated half birthday would fall on February 29th, it will be adjusted to February 28th. The calculator handles these edge cases automatically.
