How This Works
This finds the next occurrence of your birth month and day from today, and counts down live. If your birthday is February 29th, it's celebrated on February 28th in non-leap years — a common convention we apply automatically.
Formula
Days Until Birthday = Next Occurrence Of Birth Month/Day − Today
Example
If today is August 1 and your birthday is October 15, there are 75 days until you turn one year older.
