Age between two dates
Choose a birth date and an end date. You get calendar-correct years, months and days, plus lifetime totals in months, weeks, days, hours and seconds, and the countdown to the next birthday.
Your time, clearly explained
Every date you care about,
counted correctly.
Age Calculator turns a date of birth into something you can actually read: exact years, months and days, lifetime totals, the age gap between two people, and a reminder that arrives on the morning of the day itself. Everything is stored on your phone.

Six tools, one app
What Age Calculator does
Each tool answers one question well. Open the app, pick the tool, get the number.
Face age detector
Take a selfie or pick a photo and get an estimated age range. The analysis runs on your device, the photo is not uploaded or saved, and it is never attached when you share a result.
Age difference
Enter two birth dates, optionally with names, and see exactly how far apart two people are in years, months, days and total weeks — and which of the two is older.
Leap year check
Check whether any year is a leap year, see why the rule applies, and find the nearest leap years before and after it. Useful for 29 February birthdays.
Date add and subtract
Move a date forward or back by days, weeks, months or years. Handy for due dates, deadlines, notice periods, warranty ends and document expiry.
Birthday and anniversary reminders
Save birthdays, anniversaries and other dates with a name, relationship and note. Pick your reminder time and whether it arrives as a ringtone, a beep or a vibration.
Inside the app
Built to be read at a glance
Large numbers, plain labels, and a light theme that follows your system setting.
Swipe to see more screens.
Privacy by default
Your dates never leave your phone.
Age Calculator does not ask you to create an account. Saved birthdays, notes, reminder settings and calculation history are written to local storage on your device. Face-analysis photos are processed on device, are not stored by the app, and are never included in a shared result image.
No sign-up
No email, no password, no profile.
On-device storage
Delete the app and the data goes with it.
Photos not kept
Analysed, then discarded.
