Online age calculator — enter your birthday to get your exact age in years, months and days, total days and weeks lived, hours and minutes, plus a countdown to your next birthday.
❓ FAQ
How is the exact age calculated?
The tool counts complete years, remaining months and remaining days from your birth date to today, accounting for leap years and varying month lengths — the same method used on official documents.
How is the next birthday countdown calculated?
The tool compares this year's birthday to today. If it has already passed, it counts days to next year's birthday. If today is your birthday, it shows a greeting.
Are the hours and minutes estimates?
Yes. These figures are based on total days multiplied by fixed factors (1 day = 24 hours = 1440 minutes) and do not account for your exact birth time.
Does it support future dates?
No. The age calculator only accepts dates up to today — future dates cannot produce an age.
