How the count works
Count whole calendar days from a start date to a target date.
This uses the same exclusive day difference as the date calculator (Jan 1 → Jan 2 = 1 day).

What the days-until count is
This page counts whole calendar days from a start date to a target date on your local calendar. 1 January to 2 January is 1 day. Weekends and public holidays are included because the tool does not know your office calendar.
Use it for an exam date, a trip, or a deadline when you want a day count rather than a ticking clock. A target in the past is reported as already passed, not as a negative remaining count. The countdown timer is the page that updates every second while the tab stays open.
How to use it
- Set the start date. Leave it on today if you want days remaining from now.
- Set the target date. A past target produces a negative or zero span depending on the order you entered.
- Read the day count. It is a date difference, not business days.
- If you need to add or subtract days from a date, switch to the date calculator.
Both dates stay in this browser tab. Nothing is uploaded.
