Frequently asked questions
- Why is 45 minutes a common study or work block?
- It is long enough for deep focus but short enough to hold attention before it drops off, which is why many lessons and focus blocks run about this length. A short break afterward keeps the next block productive.
- How does this differ from the 30- or 60-minute timer?
- Only in length — it is the same plain countdown. Forty-five minutes tends to fit a class period or a single deep-work block, where 30 suits a meeting and 60 an hour-long session. Pick whichever matches your task.
This timer keeps the exact time even if you switch tabs. If this tab or your browser closes, nothing can alert you at the exact finish time — there's no server behind this, by design. Come back any time and we'll tell you honestly how long ago it ended.
