Days until calculator

Pick any future date and the countdown shows the days remaining from today, broken into weeks and days, plus the weekday it falls on.

Enter any date to see exactly how many days are left until it.

Pick a valid date to start the countdown.

The countdown is measured from your device's local date today to the date you choose, in whole days.

How does it work?

Days are counted in whole calendar days using UTC, so the result is unaffected by time zones or daylight saving. A negative count means the date has already passed.

Days-until formula

d=target−todayd = \text{target} - \text{today}
d
Whole days between today and the target date.
target
The date you are counting down to.
today
The current date (your local today).

From 1 June to 1 July is 30 days.

Method & sources

We count whole calendar days from today to the date you choose. Both dates are handled in UTC so time zones and daylight saving never shift the result. You pick the target date yourself — the calculator does not look up holidays or official calendars.

How we calculate

  • The count is whole days from today to the date you choose.
  • Today is your device's local date; the target date is the one you pick.
  • A negative count means the date has already passed.
  • The day of the week shown is the weekday the target date falls on.

Rounding

The countdown is in whole calendar days. Today and the target date are counted in UTC, so time zones and daylight saving never shift the result.

When it's useful

Use it for anything with a date: a trip, a deadline, an appointment, or a personal goal.

How the days are counted

The count is in whole calendar days from today to the date you pick, calculated in UTC so it never drifts with time zones or daylight saving. If the date has already passed, the count shows how many days ago it was.
