How it works
Follow these steps to get started. Each step is short so you can move quickly from upload to download.
Enter your date of birth.
Leave “as of” on today for the live clock, Birthday Countdown, and planet ages.
Share a link to send your results, not your birth date.
Set a past “as of” date to freeze the numbers at that moment.
FAQ
Is this age calculator free?
Yes. It is free to use and does not require an account.
How is age calculated?
We count calendar years, months, and days from your birth date to the “as of” date you choose.
What are ages on other planets?
A fun comparison based on how many orbits each planet would complete in your lifetime so far, not a scientific horoscope.
What does a share link include?
Your calculated ages and Birthday Countdown, not your birth date. Anyone with the link can see that snapshot.
Is my birth date sent to a server?
No. Everything runs on your device.
