1 Hour Timer
A full hour, counted down with an alarm at the end. Long enough that a timer which counts its own ticks would be minutes out by the finish — this one is not.

An hour
An hour is the unit almost everything else is expressed in — pay, billing, timetables, appointments, cooking. It is also the point at which the accuracy of a browser timer stops being a technicality. A tab that has been in the background for an hour has been throttled hard, and a timer built by counting its own ticks can be several minutes short by the end.
For an exam or a mock paper that difference is the whole point of using a timer. Practising under a clock that runs generously trains you to a pace that will not survive the real thing, and the direction of the error is always the unhelpful one.
In the kitchen an hour is a roast, a braise, a long prove or a stock. The tolerance is usually wider than a short cooking step — a minute either way on an hour-long roast changes nothing — but the case for a reliable alarm is stronger, because nobody stands over an hour-long dish and everyone leaves the room.
As a work block a full hour is longer than most people can hold one thing well. It works when the work is genuinely absorbing and much less well when it is not, which is why blocks of fifty with a real break tend to produce more over a morning than three unbroken hours do.
What people use it for
- A timed exam paper or mock
- A roast, braise, stock or long prove
- A class, a lesson or a booked hour
- Billing and timesheet blocks
- Any long unattended process where the alarm has to be right
How it works
Set to sixty minutes. Start with the button or the space bar.
This is the length where the design matters most. The finishing moment is worked out once, when you press start, and everything after that is a subtraction from the clock — so an hour in a hidden tab is an hour, not fifty-six minutes.
The alarm is scheduled at the start on the audio clock, which keeps running when the JavaScript timers around it are throttled.
Set the minutes field to 90 or 120 for longer, or add seconds for an odd figure.

Questions
Is an hour timer accurate in a background tab?
This one is. It reads the clock rather than counting, so the answer does not depend on how often the tab was allowed to run. Many timers do lose minutes over an hour, which is the specific failure this avoids.
Can I use it for a timed exam paper?
Yes, and it is one of the better uses. Practising against a clock that runs long trains the wrong pace, and the error always runs in the direction that flatters you.
Will the alarm sound if I have left the room?
It is scheduled in advance rather than fired at the end, so it sounds on time as long as the tab still exists. Allowing notifications adds a second signal that does not depend on volume.
How do I set 90 minutes?
Put 90 in the minutes field. Anything up to 1,440 minutes — a full day — works.
Can I pause it and come back later?
Yes. Pausing banks the remaining time and starting resumes from there, so the total running time is still exactly an hour.
Is an hour a good block of work?
Only for work that is genuinely absorbing. For most things fifty minutes with a real ten minute break produces more over a morning than an unbroken run does.
What if I need to count down to a specific time instead?
Use the countdown to a date, which takes a day and a time and works out the gap itself rather than asking you to do the subtraction.
