Two timers in one
Before the moment arrives it counts down; after — it counts up. That second mode is quietly the more motivating one: days since you started running, since the product launched, since the last incident. Big round numbers deserve noticing.
Planning backwards
The decimal total ("173.4 days") turns a date into a budget: divide your remaining work by the remaining days and you have a required daily pace — the honest version of "plenty of time left". Pairs well with our Date Calculator for deadline math without the live ticking.
Frequently asked questions
How do I count down to a specific date and time?
Pick the moment in the field above — the timer immediately shows the remaining days, hours, minutes and seconds, ticking live while the tab is open.
What happens after the date passes?
The timer flips to "Time since" and counts up — handy for tracking how long ago something happened, from a launch to a quit-smoking date.
How many days until New Year / my wedding / the deadline?
Exactly what this answers: the total is also shown as decimal days (e.g. "173.4 days in total"), which is useful for planning backwards from an event.
Does the countdown account for time zones?
It uses your device's local time — the countdown matches the clock on your wall. For an event in another time zone, convert it first with our Time Zone Converter (linked below).
