Enter your date of birth and (optionally) a target date. The tool computes the calendar difference using accurate month and leap-year math, then breaks the result down into years, months, days, weeks, hours and minutes. It also shows the number of days remaining until your next birthday.

Frequently asked questions
How is age calculated exactly?
Age = current date − date of birth. We subtract years, borrow months and days the same way you would on paper, accounting for varying month lengths and leap years.
Can I calculate age between any two dates?
Yes. The 'as of' date is editable, so you can find someone's age on any past or future day.
Does this tool store my date of birth?
No. All calculation happens in your browser. Nothing is uploaded or saved.
