Free 60 Minute Timer — 1 Hour Countdown

When You Need a Full Hour

A 60-minute deep work block is the extended-focus version of the Pomodoro method. Where a 25-minute Pomodoro works for task-switching work, a full hour suits tasks that require sustained concentration without interruption: writing a chapter, solving complex mathematical problems, preparing a detailed presentation, or coding a feature from scratch. The key is to protect the hour completely — no email, no messages, no interruptions.

For cooking, 60 minutes covers a roast chicken (at 200°C for a 1.5kg bird), slow-simmered tomato sauce, a batch of homemade bread dough during its first rise, or a full sous vide session for chicken breast. Use the Alarm Clock to set a reminder for when to start preheating the oven.

In education, 60 minutes is the standard university lecture length and the typical standardized test section. Students practicing under timed exam conditions benefit from using a visible fullscreen timer to simulate real test pressure.

Features

Progress bar, 15 alarm sounds, browser tab title countdown, fullscreen mode, repeat toggle, count-up past zero. The timer runs accurately for the full hour using Date.now() calculations rather than interval counting, preventing drift.
