What is the Birthday Countdown?
The birthday countdown shows how many days, hours, minutes and seconds are left until your next birthday, the age you will turn and the day of the week it falls on. It also shows your half-birthday.
For your exact age today use the Age Calculator; to share a countdown with friends, make one with the Make Your Own Countdown.
