How old am I?
Your age — counted in years, and in every second since.
Questions
How old am I if I was born in a certain year?
Subtract your birth year from the current year, then take away one if your birthday hasn't happened yet this year. Enter your full date of birth above for the exact answer.
How many days old am I?
Enter your date of birth and the counter shows the number of full days you have been alive, along with weeks, hours, minutes and seconds — updating live.
Why does the seconds count assume midnight?
Most people don't know the minute they were born, so the live counter starts from midnight on your birth date in your own time zone. Add your birth time for a more exact figure.
