Age Calculator – How Old Am I?
Your exact age in years, months and days, plus total days, weeks and hours lived, the weekday you were born and a countdown to your next birthday.
How age is calculated
Your age is counted in completed years, then the months and days since your last birthday. Leap years are taken into account, and people born on 29 February celebrate on 28 February in common years for the countdown. Change “Age on” to find out how old you were – or will be – on any other date.
