About this tool
Age is more than a single number. Forms may ask for age in years, a visa may ask for age in months, and a child's milestones are often tracked in weeks. This calculator gives all of these from one date.
It counts full calendar years and months, then the remaining days, and also shows total months, weeks, days and hours. Use the second date to find someone's age at a past or future date, for example to check eligibility on a deadline. If you were born on 29 February, your birthday is counted on 1 March in non-leap years.
Frequently asked questions

Can I find my age on a future date?
Yes. Enter the future date in the second field to see how old you will be on that day.
What if I was born on 29 February?
In non-leap years the birthday is counted on 1 March.
