Free Countdown Timer
Live countdown to any future date and time.
Select a date above to start the countdown.
A countdown timer is a free online tool that shows exactly how much time remains until a specific date and time. Enter your target date — a birthday, deadline, vacation, exam, or any event — and watch a live second-by-second countdown in days, hours, minutes, and seconds.
How it works
The timer compares the current time from your device clock to the target date and time you entered. It calculates the difference in milliseconds and displays it as days, hours, minutes, and seconds. The display refreshes every second so the countdown is always accurate. An optional start date lets you track progress as a percentage, showing a visual progress bar that fills as the target approaches.
Because the timer uses your local device clock, it works offline after the first page load and requires no internet connection to keep counting. Your target date is not stored on any server. When the countdown reaches zero, a visual indicator confirms the event has arrived and the page title changes to "Time is up!" Quick presets for Christmas, New Year, this weekend, Friday 5 PM, and Summer let you start a countdown with a single click — no date entry required. An optional event name display personalizes the countdown.
The timer also updates your browser tab title with the remaining time (e.g. "15d 08h - Countdown Timer"), making it easy to glance at the tab to see how much time is left. A fun units display shows the same countdown in weeks, sleeps, and total hours for a different perspective. You can save your event to revisit later or share a link with the date pre-filled for friends and family.
When to use a countdown timer
Common uses include counting down to a holiday (Christmas, New Year's, Thanksgiving), a sports event or concert, a school exam, a work deadline, a wedding or anniversary, a product launch, or a birthday. The timer works equally well for near-future events (hours away) and distant ones (years away). The large, clear display makes it readable from across the room — perfect for projecting on a screen during an event countdown or displaying on a tablet at a wedding reception.
Countdown timers also build anticipation — share a countdown link with friends and family before a big trip, use it as a visual aid during goal-setting sessions, or keep it open on a secondary monitor to maintain deadline awareness throughout the workday. The visual countdown creates urgency and excitement better than a static date ever could. Students preparing for exams use it to track time remaining until test day, helping them structure their study schedule backward from the deadline. Product managers and marketers use countdowns to build hype for launches, and travelers use them to count down the days — and eventually the hours and minutes — until departure.

How many days until Christmas?
Christmas falls on December 25 every year.

In June 2025, there are approximately 203 days remaining until December 25, 2025.
How many hours until tomorrow?
The number of hours until tomorrow depends on the current time. If it's 3:00pm now, there are 9 hours until midnight and the start of tomorrow. To see an exact countdown to any specific time tomorrow, enter tomorrow's date and your target time (such as 9:00am) into the countdown timer above for a live seconds-precise display.
Can I use this countdown timer for a work deadline or event?
Yes — enter any future date and time as your deadline. The countdown displays the exact time remaining in days, hours, minutes, and seconds. Save it with a custom name like 'Project Due' and it stays saved across sessions. The countdown also works for past dates, showing how long ago an event occurred.
What happens when the countdown reaches zero?
When the countdown hits zero, the timer displays a completion message and plays an optional alert sound. The display switches to show how much time has elapsed since the target date, so you can see how long ago the event occurred. This is useful for tracking how many days since an event rather than how many days until it.
