Days until your project deadline

Pick your project deadline and the countdown shows the days remaining from today, broken into weeks and days, plus the weekday it falls on.

Enter your deadline to see exactly how many days are left to deliver.

Pick a valid date to start the countdown.

The countdown is measured from your device's local date today to the deadline 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.

What this countdown does

A deadline is easier to manage when it's a number, not a vague 'soon'. This countdown turns your deadline into the days remaining and breaks it into weeks and days, so you can size the work and pace the team.

How to use it

  1. Pick the date you're counting down to.
  2. Read the days remaining at the top.
  3. Check the weeks-and-days breakdown and the weekday it falls on.
  4. Use Share to send the live countdown to anyone.

When it's useful

Use it for sprint planning, to set internal checkpoints ahead of the real date, and to keep stakeholders honest about what's left.

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.
