Common questions

Are DevsLoad calculators free?

Yes. The calculators are free to use and do not require an account.

Are my dates uploaded?

No. The age calculator runs locally in your browser, so the dates you enter are not sent to DevsLoad.

Can I use the age calculator for a future date?

Yes. Choose any reference date on or after the date of birth to calculate age on that specific date.
