Birthday Countdown
How long until my birthday?
A live countdown to the next one — days, hours, minutes and seconds, ticking down, with the age you will turn.
Questions people ask
The things that come up about birthday countdowns, answered plainly.
What happens on the day itself?
The countdown reaches zero and the page says happy birthday, then starts counting to next year at the end of the day.
Can I share the countdown?
Yes — the address bar always holds the current state, so copying the link and sending it gives the other person the same countdown.
