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.

How to use

Enter the date of the event.
If you are not counting from today, set a different starting date.
Read off how many days are left or have passed, and the same span in weeks, months and hours.

Counting from 22 September 2026

Each row is a separate run with 22 September 2026 as the starting date. Working days here are the five-sevenths estimate, without public holidays.

Every row comes from the calculator on this page.

What this calculator shows

The exact day count and whether it is remaining or elapsed
The same span in weeks, months and hours
An approximate count of working days in the interval

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?

Public holidays are not deducted: the working-day figure is a five-sevenths estimate. 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.

How many days are there from 22 September to New Year?

101 days to 1 January 2027, and exactly 100 to 31 December 2026.

How do I see how many hours are left?

The calculator multiplies the days by 24: 100 days is 2,400 hours. It ignores the time of day; for an exact span in hours and minutes, use the time duration calculator.
