Use Cases

Shareable Countdown for Events and Launches

Planning a product launch or a wedding? Add the event, click Share, and send the URL to your team or guests. Anyone who opens the link sees the exact same countdown restored, making it perfect for remote team deadlines.

Countdown Timer with Browser Notifications

For time-sensitive tasks like cooking, meetings, or exam sessions, enable the Notify Me option. A desktop alert fires automatically when the timer hits zero — even if you've switched to another tab or minimized the browser. For structured work sessions with built-in break intervals, the Pomodoro timer is purpose-built for that workflow.

Multiple Event Countdown Timer

Tracking several deadlines at once? Add up to five named timers simultaneously. Each card is independent, so you can monitor a sprint deadline, a client delivery, and a personal goal all on the same screen.

Time Since Counter for Habits and Milestones

Flip any timer to Time Since mode to count upward from a past date. Track sobriety streaks, workout consistency, relationship anniversaries, or how long a production system has been running without downtime. To find the exact number of years, months, and days between any two dates, try the age calculator.

FAQ's

You can run up to 5 named countdown timers simultaneously. Each appears as its own card showing Days, Hours, Minutes, and Seconds. Remove any card with the Remove button to free up space for a new timer.
Timer data is encoded in the page URL hash, not in cookies or localStorage. As long as you bookmark or share the URL before closing, your timers will be fully restored when the link is reopened. Browser notifications, however, require the tab to remain open until the timer fires.
Click the Share button on any timer card to reveal a pre-built URL. Copy that URL and send it via email, chat, or social media. Anyone who opens the link will see the same countdown timers automatically restored in their browser.
Browser notifications require you to click Notify Me and grant permission in the browser prompt. If you already denied permission, reset it in your browser's site settings (usually under the padlock icon in the address bar). Notifications also require the tab to stay open until the timer expires.
Time Since mode counts upward from a past date, showing exactly how much time has elapsed since that moment. It is ideal for tracking sobriety streaks, relationship anniversaries, days since a project started, or how long a server has been running without downtime.
Yes. After the page loads, all countdown logic runs entirely in your browser with no server communication required. The timers continue ticking without an internet connection — only the initial page load needs network access.
Yes. The date-time picker lets you set any date and time combination. If you only care about the day, simply set the time to midnight (00:00). The timer will count down to the start of that day in your local timezone.
