Counts forwards and backwards from any date

Days, weeks and months until an event, or since it, if the date has already passed.

Countdowns come up constantly: to a holiday, a deadline, a New Year, the end of a contract. Doing it mentally is awkward because months differ in length and leap years intrude, and being a day out on a deadline is expensive.

The count starts from today by default, but the starting point can be moved to any date. That is handy for measuring the gap between two past events or planning forward from a future one.

What this calculator shows

The exact day count and whether it is remaining or elapsed
The same span in weeks, months and hours

What to keep in mind

Months use 30.44 days, the yearly average, so use the date difference calculator when whole months matter.
Working days are estimated as five sevenths of the total; public holidays are not deducted.

FAQs

How do I count days since a date?

Enter the past date as the target — the result comes back negative and labelled as elapsed. No separate tool is needed.

Why is the month count a decimal?

Because months vary in length, so an average of 30.44 days is used. For whole months, use the date difference calculator.

Are public holidays counted?

No, the working-day figure is a five-sevenths approximation. The work calendar handles holidays and transfers properly.

Is today included?

No, this is the difference between two dates. Add one if you want the starting day counted as well.
