How to calculate age from a date of birth

  1. 1

    Enter the date of birth

    Tap the date field and choose the day, month and year of birth.

  2. 2

    Choose the date to calculate for

    Age is calculated for today by default. Change the date to get the age on a specific day, such as an application deadline or a trip.

  3. 3

    Read the exact age

    You get the age in years, months and days, the total months, weeks, days and hours lived, the weekday of birth and a countdown to the next birthday.

How age is calculated

Age in completed years is the number of birthdays that have passed. The months and days show the time since the last birthday: someone born on March 15, 1990 is 36 years, 6 months and 15 days old on September 30, 2026. Dates are handled as whole days, so time zones and time of birth do not change the result.

People born on February 29 have their birthday on February 28 in non-leap years in this calculator. Some laws use March 1 instead; the difference is a single day.

When you need an exact age

Applications, insurance, school enrollment and sports categories often ask for the age on a reference date rather than today. That is why you can change the date: find out, for example, whether a child will be 5 by September 1.

  • Minimum ages for jobs, licenses and retirement
  • Age in months for babies and check-ups
  • Countdown to the next birthday
  • Fun facts: how many days or hours you have lived

Age calculator: frequently asked questions

How do I calculate my exact age?

Subtract your birth year from the current year and take away 1 if this year's birthday has not happened yet. For months and days, count from the last birthday. The calculator does all of this from your date of birth.

How old is someone born in 2000?

Subtract 2000 from the current year: in 2026 they turn 26 on their birthday (27 in 2027). Before the birthday they are a year younger. The table on this page shows every birth year.

How many days old am I?

Enter your date of birth: the result shows the total days lived, plus weeks, months and an estimate in hours.

Can I calculate age on a past or future date?

Yes. Change "Age on" to the date you need, for example the cut-off date of an application, and the age is calculated for that day.

Is my date of birth stored?

No. The calculation runs in your browser and your date of birth is never sent to or stored on a server.
