If your date is February 29, choose whether to celebrate on February 28 or March 1 in non-leap years.

Anniversary Countdown: practical tips
Enter the original date, not the next occurrence. The timer finds the next yearly anniversary and shows the milestone year based on the date you first celebrated.
01
Check the starting year
The original year determines how many years together the next anniversary represents. If the milestone looks wrong, confirm that the entered date is your starting date.
02
Choose a leap-day convention
For a February 29 anniversary, decide whether February 28 or March 1 feels right in years without a leap day. The choice changes the next target date.
03
Plan outside the timer
Use the days remaining to decide when to book or prepare something meaningful. Add a separate calendar reminder if you need an alert when the page is closed.
Make the result useful
- Double-check the original year if you want the milestone number.
- Use the date you personally celebrate.
- Keep a separate calendar reminder if you need a notification.
