How it works
Enter your date of birth to see your exact age in years, months and days, the day of the week you were born on and how long it is until your next birthday. The summary shows your age in total months, weeks, days, hours and minutes. You can also calculate the age on any other date.
Calculations run locally in your browser. Results are for information only — for engineering, electrical or financial decisions, verify the assumptions and applicable standards.
