Free Countdown Timer Online — Set Any Duration

Set a custom countdown from 1 minute to 24 hours. Whether you need 10 minutes for a quiz review or 3 hours for a mock exam, our countdown timer adapts to your needs — with audio alerts, pause/resume, and automatic session logging.

Custom Duration Timer

Unlike fixed Pomodoro timers (locked to 25-minute intervals), a countdown timer lets you set the exact time you need. This is ideal for timed assignments, practice exams, cooking, workouts, or any task with a hard deadline.

How to Use the Countdown Timer

1. Set the duration — Enter hours, minutes, or both.
2. Press start — The timer counts down with large, clear digits.
3. Pause if needed — Hit pause to take a break without losing progress.
4. Alarm sounds — A configurable alarm plays when time is up.
5. Session saved — The completed session is logged to your history.

Countdown Timer vs. Stopwatch vs. Pomodoro

Use a countdown timer when you know exactly how long you need. Use a stopwatch when you want open-ended tracking. Use the Pomodoro timer for structured intervals with automatic breaks. All three modes are available in StudiesTimer — switch anytime without losing your session history.
