Frequently Asked Questions
How many days until my birthday?
Enter your date of birth and the calculator counts the days from today to your next birthday, shows the weekday it lands on, and the age you will turn. It updates automatically each day you visit.
What happens if I was born on February 29?
In years that are not leap years, your birthday is shown on February 28 by default. In leap years it stays on February 29.
Is my date of birth saved?
It is stored only in your browser so this and the Age calculator can pre-fill it. It is never uploaded anywhere. Clear it any time with "Forget my data".
What is a birthday countdown and how does it work?
A birthday countdown shows the number of days remaining until your next birthday. Enter your date of birth and the count starts instantly, updating each day you return to the page.
What weekday will my next birthday fall on?
Along with the days remaining, the calculator shows the exact day of the week — for example Saturday — that your next birthday lands on, so you can start planning.
What happens after my birthday passes?
Once your birthday has passed, the countdown automatically rolls over and begins counting down the days to next year's birthday.
