Birthday Countdown — Days Until Your Next Birthday
The Birthday Countdown Calculator tells you exactly how many days are left until your next birthday. Enter your birth month and day, and the calculator automatically finds the next occurrence of your birthday — whether it is later this year or next year — and counts the days remaining from today.
Frequently Asked Questions
If today is your birthday, the calculator returns 0, meaning there are 0 days remaining — it is today! Alternatively, it may show 365 (or 366 in a leap year) as the days until the same date next year, depending on exact midnight timing.
