Age Calculator BR
Work out your exact age in years, months and days — plus weeks, days, hours and a birthday countdown.
How it works
Enter your date of birth (and optionally a second date to find your age on that day). The calculator returns your exact age in years, months and days, the totals in months, weeks, days and hours, the weekday you were born on, and the number of days until your next birthday.
Frequently asked questions
How is exact age calculated?
The tool counts the whole years from your birth date, then the remaining whole months, then the leftover days — accounting for different month lengths and leap years.
Can I find my age on a past or future date?
Yes. Fill in the second ‘age at date’ field and the calculator works out your age on that specific day.
Does it handle leap years?
Yes. The day and month totals use real calendar dates, so leap years are included automatically.
