Count how many days, weeks, months and hours remain until any date — a birthday, holiday, wedding, exam or deadline.

The tool compares today (in your browser's timezone) with the date you pick. It counts calendar midnights between the two dates, then also shows the same gap as weeks, months (average 30.44 days), hours and minutes.
Time zones and “part of today” matter. If it is 11 p.m. on Monday and the event is Wednesday morning, some people say “1 day” and others say “2 days”. This calculator uses whole calendar dates in your local timezone, which matches how most “days until Christmas” pages work.
If you pick a date that already happened, the tool shows how many days have passed since that date instead of a countdown.
The countdown runs in your browser. The date you pick is never sent to any server and never stored.
The tool takes today's date in your local timezone and subtracts it from the target date, counting midnights in between. Hours and minutes use the time remaining until midnight at the start of that date.
Yes. It uses the timezone of the device you are on. Someone in Tokyo and someone in New York can see a different 'days left' for the same calendar date if it is already the next day on one side of the world.
You will see how many days have passed since that date, labelled clearly as a past event — useful for anniversaries.
Days and weeks are exact. The months figure is an average (365.25 / 12 ≈ 30.44 days) so February and 31-day months stay simple. Use days when you need a precise deadline.
Yes. Use the preset buttons. Christmas and New Year roll to next year automatically after the date has passed.
Yes. Everything runs locally in your browser. Nothing is uploaded or stored.
