How to use it

  1. Enter your date of birth. Use the date on your birth certificate, passport or ID, the one the application asks for.
  2. Set the "age on" date. It starts at today. To check an application, change it to the cut-off date it gives.
  3. Add the age limit (optional). Type the minimum and maximum age to see whether you're eligible, and the range of birth dates that qualify.

For the best result

  • Use the cut-off date. Age limits are usually counted on a fixed date given in the rules, not on the day you apply.
  • Match your documents. Use the same date of birth that's on the certificate you'll upload.
  • Keep a note. Copy result gives you a short summary to save or share.
  • Applying now? The photo & signature resizer gets your photo and signature to the exact size the form asks for.

Questions

How do I check if I'm within an age limit?

Enter your date of birth, set "Age on" to the cut-off date, and type the minimum and maximum age. The tool shows your exact age on that date and whether you're within the limit.

What does "maximum age 30" mean here?

This calculator reads it strictly: on the cut-off date you can be at most exactly 30 years, 0 months and 0 days. If you're even a day older, it shows how much you're over. Some rules word their limits differently, so always follow the official wording.

How is the age counted?

In whole calendar years and months, then the remaining days, the way it's done on official forms. For example, from 15 March 2000 to 1 January 2026 is 25 years, 9 months and 17 days.

What if I was born on 29 February?

In years without 29 February, your birthday is counted as 28 February.

Is my date of birth saved or sent anywhere?

No. The calculation happens on your device, and nothing is stored or sent.
