Countdown Timer
Enter a target date and time to see a live countdown of the days, hours, minutes and seconds remaining, updated every second. Pick a date in the past and it automatically switches to a count-up of elapsed time.
Tips for the countdown timer
- Enter the date and start time of an upcoming event to see exactly how much time is left, down to the second. Keep the browser tab open and the numbers keep ticking down in real time.
- Use the "Rest of today" button to instantly set the target to 23:59:59 today — handy for checking how much time remains before an end-of-day deadline.
- Enter a date in the past and the tool automatically switches to a count-up display, showing elapsed time since that moment — great for tracking days since an anniversary or milestone.
- Because the input accepts a specific time as well as a date, you can set a precise reference moment such as "January 1, 00:00" rather than just a day.

Side Note — countdowns and humanity's culture of waiting
One of the reasons the countdown became a familiar concept worldwide is the rocket-launch sequence of "10, 9, 8...". This dramatic device was first used in the 1929 German film "Woman in the Moon" (Frau im Mond) and later became a genuine tool in real space programs to build tension and synchronize a launch team's actions.
New Year's Eve countdown events are beloved across cultures too. The "ball drop" in New York's Times Square has continued since 1907, turning the instant the calendar flips over into a shared social experience that goes far beyond simply announcing the time.
Psychologically, making the remaining time visible is known to trigger what's sometimes called the "deadline effect" — a boost in motivation. The more concretely a countdown is expressed as a number, the more it tends to sharpen a person's focus.
