How Many Days Until My Birthday?
Enter your date of birth and get a live countdown to your next birthday, including the exact date and weekday.
Never lose track of your own birthday countdown
Whether you are planning a trip, booking a venue, or just counting down for fun, this tool tells you exactly how many days are left until your next birthday, right down to the day it falls on and what weekday that will be.
If your birthday already passed this year, the calculator automatically counts forward to next year's date instead of giving you a negative number.
A quick note on leap day birthdays
If you were born on February 29, this calculator treats February 28 as your observed birthday in years that are not leap years, then switches back to February 29 in the next leap year. That keeps the countdown consistent every single year.
