1 Hour Timer Online

Need exactly one hour? This free 1 hour timer starts at 60:00 and counts down to zero directly in your browser.

Press Start to begin the countdown. When the hour is over, the timer alerts you that time is up. Reset or restart it whenever you need another 60 minute countdown.

There is nothing to install and no account is required. Use it for deep work, studying, workouts, meetings, cooking or any task that needs a full hour.

How Long Is 1 Hour?

1 hour is equal to 60 minutes or 3,600 seconds.

It is a full sixty-minute block, making it useful for longer tasks, study sessions, exercise, focused work and activities that need more uninterrupted time.

What Can You Do in 1 Hour?

A one hour countdown gives you enough time for a substantial work session, workout or project while still giving the activity a clear end point.

  • Complete a deep work session
  • Study without interruptions
  • Do a full workout or gym session
  • Attend or run a meeting
  • Cook or bake longer recipes
  • Clean and organise your home
  • Read, write or practise a skill
  • Work on a personal project

1 Hour Timer for Deep Work and Studying

An hour gives you enough uninterrupted time to make meaningful progress on a demanding task. Choose one priority, start the timer and work until the countdown ends before taking a break or reviewing your progress.

If you prefer shorter structured work intervals with regular breaks, try our Pomodoro Timer.

1 Hour Timer for Workouts and Longer Tasks

A 60 minute timer is also useful for gym sessions, walking, yoga, cleaning, cooking or project work. Starting a countdown lets you concentrate on the activity instead of repeatedly checking how much time has passed.

1 Hour Timer vs. 1 Hour Alarm

A timer counts down for a specific duration. This page starts with one hour and alerts you when sixty minutes have passed.

An alarm is set for a specific time of day. If you want an alert at a particular clock time instead, use our Online Alarm Clock.
