Live countdown to any moment
The timer ticks every second so you always know exactly how long is left — down to the second.

Runs entirely in your browser using your device clock — nothing is saved, logged or sent anywhere.
A countdown calculator (also called a countdown timer or "days until" calculator) tells you exactly how much time remains until a future date and time. Instead of counting on a calendar, you get a live display in days, hours, minutes and seconds that updates every second — building anticipation for whatever you're waiting for.
Americans search for countdowns to all kinds of moments: "how many days until Christmas," "days until summer," "countdown to my birthday," "days until the new year," exam and assignment deadlines, wedding and due-date countdowns, vacation and concert dates, product and game launches, payday, retirement, and even the next federal holiday or three-day weekend. This tool handles every one of them — just type the date or tap a preset.
Under the hood, the calculator compares your target date and time to your device's current clock and breaks the difference into whole days, hours, minutes and seconds. Because it reads the time live, the seconds visibly tick down, and when the moment arrives the timer announces that your event is here. It also shows handy totals — the event in total hours, minutes and seconds — which is useful for planning, scheduling and project deadlines.
Everything is calculated locally in your browser, so it's fast, works offline once loaded, and keeps your events completely private. Bookmark the page with your date selected to check back anytime.
