Countdown to a Date

Count down the days until a birthday, holiday, deadline, or any future event.

How to use countdown to a date

  1. Choose your target date
  2. See the number of calendar days from today
  3. Check the target weekday before saving a reminder

Worked example

Target October 20, reference October 14, 2026

6 calendar days remaining

How the result is calculated

Today is day zero. Tomorrow is one calendar day away, regardless of whether a local daylight-saving change makes the elapsed interval 23 or 25 hours. Past targets show days ago.

Inputs stay in your browser. You can use this tool without joining the waitlist or creating an account.

Frequently asked questions

How many days until my event?
Pick your target date and the countdown shows the exact number of days remaining from today, plus the same gap in weeks and months and the weekday the date lands on.
Can I count down to a birthday or holiday?
Yes - set the date to any birthday, holiday, exam, vacation, or deadline. If the date has already passed, the tool tells you how many days ago it was instead.
Can I keep the countdown on my iPhone?
Yes. The Monthly Calendar Widgets countdown widget keeps the days-left number on your Lock Screen, so your most important date is always one glance away.
