Date & Time
Days Until Calculator
The Days Until Calculator counts down the exact number of days from today to any future date — a holiday, birthday, wedding, exam, product launch, or deadline. Pick a target date and you'll instantly see the total days remaining, plus a years / months / weeks / days breakdown. It works for past dates too, showing how many days ago something happened — and it runs entirely in your browser, with no signup and no data leaving your device.

How the day count is calculated
The result is the number of whole calendar days between today and your target date, counted from midnight to midnight in your device's local time zone. Today counts as day zero, so a date set to tomorrow shows 1 day.
The years / months / weeks / days breakdown is a calendar-accurate split (it accounts for months of different lengths and leap years), not a simple division — so "1 month" means one calendar month, not 30 days.
Past dates are supported: pick a date that has already happened and the tool shows how many days ago it was instead of a countdown.
