What is a days-until calculator?
A days-until calculator counts how many days remain from a start date to a future date — handy for holidays, exams, deadlines, weddings and launches.
How it's calculated
It counts the whole calendar days from the start date to the target date, using UTC so daylight saving never affects the total. If the date has already passed, it shows how many days ago it was.
Example
There are 121 days from 1 September to 31 December.

How to use
Pick a target date or tap one of the quick presets. The result shows the number of days from today, plus an approximate weeks and months breakdown.
If you choose a past date, the calculator instead shows how many days have passed since then — useful for anniversaries or tracking time since an event.
