How many days until my birthday?
Enter your date of birth above. The calculator counts the days from today until your next birthday.
What if my birthday is today?
If today is your birthday, the calculator treats today as your birthday and shows zero days remaining.
Does the calculator work for leap-day birthdays?
Yes. For birthdays on February 29, the calculator uses February 28 in years that do not contain a February 29.
