Timing a full movie at home
You press start when the opening credits roll. Two hours later, the alarm sounds. That is the whole idea. The countdown reads from your computer's clock, not from a chain of ticks, so it stays correct even if you switch tabs or your device goes to sleep. The tab title shows the time left, so you can glance at another tab and still see it.
Two hours is a common block for several real tasks:
- A movie, which usually runs about two hours.
- A long study or reading session, often split into shorter sprints inside the block.
- A workshop, lab, or exam section that fills a two hour slot.
- A slow cook or bake step that needs a steady two hour window.
You can change the length without leaving the page. Type a new duration in any of these forms: 90m, 1h 30m, 1:30:00, or 2h. To count down to an exact clock time instead, enter something like 9:00 pm or 21:00. The timer then works out how long is left and counts down to that moment.
The alarm is made in your browser, so nothing downloads. Pick beeps, a chime, or silent mode with a flashing tab title. Space starts and pauses. A running timer survives a page reload on the same page, because the end time is stored for that tab.
When two hours is the right block
Some tasks need a longer stretch than a Pomodoro focus block. A two hour timer fits when the work itself takes that long, or when you want one clean window with no breaks built in.
If you want shorter focus rounds, the Pomodoro timer splits work into 25 minute pieces. For a plain countdown with no structure, the countdown page does the same job. The stopwatch counts up instead, which is better when you do not know how long something will take.
To run a two hour block right now, set the duration and press start. The clock handles the rest.
