Frequently Asked Questions

How does this calculator count days until a date?

It counts the exact number of calendar days between today and the future date you enter, using today's actual date each time the page is loaded.

Does it count today as day zero or day one?

Today counts as day zero — the countdown reaches 0 on the target date itself, not the day before.

What if I enter a date that's already passed?

The calculator still works — it shows how many days since that date instead, since a past date has a negative days-until value.
