Find your exact age from your birthday and see the countdown to your next birthday.
Leave blank to calculate from your birthday to today.
Choose your start and comparison dates to see the elapsed years, months, and days here.
Your age is also shown as total months, weeks, days, hours, and minutes lived, so you can see exactly how many days you have been alive.
The birthday age calculator converts a birthday into an exact age today or on a selected date.
It also shows birthday details that are useful for profiles, invitations, milestones, and quick personal date checks.
Alongside the calendar result, your age is broken down into total months, weeks, days, hours, and minutes lived. These running totals answer questions like how many days you have been alive or how many months old a baby is, and they update the moment you change a date so you can copy the exact figure you need.
Beyond the exact age, the birthday view answers everyday planning questions:
Need a particular result? Use the age calculator by date for any past or future day, the exact age calculator for years, months, days, hours, and minutes, or the date difference calculator to find the duration between two dates.
Birthday calculations are performed client-side, so your birthday is not uploaded or stored.
