About this tool
Runs entirely in your browser — no account, no notifications, no tracking.
How it works
A countdown is live subtraction: target date and time minus right now, split into days, hours, minutes and seconds. The only subtlety is that ‘now’ keeps moving, so the display refreshes every second from your browser’s clock — no server involved.
Time zones matter more than people expect. ‘Midnight on New Year’s Eve’ is a different instant in Sydney than in London, 11 hours apart. This tool counts down in your browser’s local time zone; if the event is elsewhere, convert it first with the World Clock tool.
For long countdowns the tool shows total days rather than calendar months, because months are irregular. ‘90 days away’ is exact; ‘3 months away’ depends on which months.
Worked examples
Product launch: Launch at 9:00 AM on Nov 1, checked Oct 5 at 9:47 PM: 26 days, 11 hours and 13 minutes left — enough for one more QA pass.
Birthday planning: Birthday on Dec 25, checked Oct 5: 81 days away. The tool also shows the weekday it lands on, handy for party planning.
