Frequently Asked Questions

What if I enter the dates in reverse order?

No problem — the tool puts the earlier date first and finds the difference, so the answer is always positive.

Can I find the difference up to today's date?

Yes — choose today's date as the second date, for example to find the total length of a job or service period.

Is the leap year (29 Feb) calculation correct?

Yes — the count follows the real calendar, including leap years.
