  2. The countdown repeats every year and shows the age being turned when a birth year is given.
  3. Copy the shareable link to send it to friends — it opens with the same birthday.

February 29 birthdays are counted on February 28 in common years.

Frequently asked questions

How many days until my birthday?

Enter your birth month and day above and the countdown shows the exact days, hours, minutes and seconds, plus how many sleeps are left.

Is my birthday stored anywhere?

Only in your own browser's local storage. Nothing is sent to a server; the shareable link carries the date in the URL.

What about leap-day birthdays?

If you were born on February 29, the countdown uses February 28 in years without a leap day.
