Set a countdown with a visual progress ring, quick-add presets, and an optional audio alert.
The Countdown Timer lets you create live countdowns to any future date. Each countdown shows days, hours, minutes, and seconds remaining — all updating every second. Create separate countdowns for deadlines, birthdays, trips, exams, or personal milestones. Each countdown gets a color-coded card for easy identification. When a countdown reaches zero, it displays a celebration message. All countdowns persist in your browser's localStorage, so they survive page reloads and browser restarts. Target dates also appear on the Unified Calendar automatically.
Live-updating display
Every countdown updates every second, showing the exact remaining time in days, hours, minutes, and seconds. The display is always current.
Multiple simultaneous countdowns
Create as many countdowns as you need. Each gets its own card with independent timing. Track deadlines, birthdays, and events all at once.
Color-coded cards
Countdowns cycle through six distinct colors — yellow, blue, pink, green, orange, and violet — making it easy to visually distinguish between different events.
Celebration on completion
When a countdown reaches zero, the card displays a celebration message. This provides a small moment of recognition for reaching a deadline or milestone.
Calendar integration
Countdown target dates automatically appear on the Unified Calendar as orange markers, so you can see upcoming events in the context of your full schedule.
Persistent and private
All countdowns save to localStorage and persist between browser sessions. No account required. No data leaves your device.
