Countdown To A Date
Build a countdown to any date and time — a birthday, a launch, an event. Or jump to a quick preset below.
Count down to anything
Pick any future date (and, optionally, a time — it defaults to midnight), give it a label if you like, and press Start Countdown. The display updates live in days, hours, minutes, and seconds down to zero. The quick preset buttons jump straight to the next New Year, Christmas, Halloween, or Valentine's Day, calculated automatically from today's date.
Looking for a countdown from a fixed length of time instead of to a specific date — like 25 minutes from now? Use the countdown timer instead.
What's the difference between this and the timer?
This counts down to a specific calendar date and time (like "March 3rd at 9am"). The timer counts down a fixed duration (like "25 minutes from now").
Can I count down to a date and time in the past?
No, if the date and time you pick has already passed, the day count will show 0 — pick a future date.
Does it keep counting if I close the tab?
No — since it runs in your browser, the countdown display only updates while this page is open. Reopening it will show the correct remaining time either way, since it's calculated from the current date.
An event countdown uses an absolute date
Enter the event date and time in your device’s local zone. The result measures time until that instant, so a “day” in the remaining duration is a block of 24 hours rather than a calendar date boundary. Across a daylight-saving transition, the number of hours between two local midnights can differ from 24.
Before sharing an event link, check its target date and label. New shared links preserve the UTC instant, so recipients in different time zones count down to the same event. Older date/time links are interpreted in each recipient’s local zone. A countdown is a visual display and does not promise an alarm at the target. Use the time-zone converter to resolve an event defined in another city before setting the local target.
