Frequently asked questions
How is exact age calculated?
Age is worked out by subtracting your date of birth from the chosen date, adjusting for the number of days in each month and for leap years. That gives your precise age in complete years, months and days, rather than a rounded figure.
Does it account for leap years?
Yes. The total-days count uses the real calendar, so the 29th of February in leap years is included. This makes the days, weeks and hours figures accurate.
Can I find my age on a past or future date?
Yes. Change the second date to any past or future date to see how old you were or will be on that day. This is handy for forms, eligibility checks and planning.
Is my date of birth stored anywhere?
No. Everything is calculated in your browser. Your date of birth is never uploaded or saved on any server.
How is the zodiac sign decided?
The zodiac (sun) sign is based on the standard western date ranges for each sign. It is shown as a fun extra alongside your age.
