How age is calculated
Your age is the time from your date of birth to today, counted in whole years, then the leftover months and days. This calculator also totals your entire life in months, weeks, and days, tells you which weekday you were born on, and counts down to your next birthday.
Questions
How do I calculate age from date of birth?
Subtract the birth year from the current year, then adjust if the birthday has not happened yet this year. This tool handles leap years and gives an exact years, months, and days result.
Can I find my age on a past or future date?
Yes. Use the second date field to calculate your age on any date, not just today.
What day of the week was I born?
Enter your date of birth and the tool shows the weekday you were born under your age.
