Days Until
Calculate how many days until (or since) any date
About Days Until
Shows how many days are left until a date you pick, or how many have passed since it, along with the weekday it falls on, the number of complete weeks and an approximate count of months. The calendar spans from 100 years back to ten years ahead, enough for release deadlines, certificate or domain expirations, anniversaries and event countdowns.

Frequently asked questions
How is today's date determined?
▾
The tool uses your device's local date. If you need to calculate from a different reference date, use the Date Difference tool instead.
What if the target date has already passed?
▾
The result switches to how many days ago the date was, shown in red instead of green, so you can track past events as well as upcoming ones. Picking today's date shows 0 and marks it as today.
Does it account for leap years?
▾
Yes. Day counting uses standard calendar arithmetic, so February 29 on leap years is correctly handled.
How are the weeks and months calculated?
▾
Weeks are the number of complete 7-day weeks in the day count. Months are an approximation: the days divided by 30.44, the average month length, rounded to the nearest whole number.
