Six hours is the length of a school day, the standard half-day session, a six-hour fasting window for some intermittent fasting variants, and a typical retail or hospitality shift. It is also the maximum length most domestic ovens recommend for low-and-slow roasting. This page sets a 6-hour timer server-side, so the countdown survives device restarts, tab closes, and screen locks. Press start, label the block ("school day", "fast", "shift", "slow roast") and pick a notification channel — Telegram, browser push, or email — and the alert arrives at exactly the right moment. Useful for shifts where your phone may be in a locker, fasting windows where you are not at the device, or roasts where the kitchen door has been closed for hours. For a longer block, the 8-hour and 12-hour timers cover full work days and longer fasts; for shorter, the 4-hour timer is one click away. Save the 6-hour block as a recurring weekday reminder if it is the structure of your day — a school day, a recurring shift, a daily 18:6 fast.

FAQ

Is the 6-hour timer good for intermittent fasting?
Yes. Some IF variants use a 6-hour eating window (18:6) or a 6-hour fast between meals. Set the timer when the window opens or closes; the notification arrives at the next transition.
Will the 6-hour timer survive a closed tab?
Yes. The countdown is scheduled server-side, so it is not tied to a browser session, tab, or device.
Can I use it for a long oven roast?
Yes — set 6 hours, label "slow roast", and the notification arrives via Telegram, push, or email when the time is up. Useful for low-and-slow cuts that need hands-off cooking.
Can I make 6 hours recurring?
Yes. After one run, save it as a daily, weekday, or weekly reminder.
