Thirty minutes is the duration that splits a working hour cleanly in two. It is long enough for a real piece of writing, a full circuit workout, a roast in the oven, or a focused reading session — but short enough that you can fit two or three of them around meetings and meals. The timer on this page is built for those longer blocks. Set the duration, pick a notification channel — Telegram, browser push, or email — and start. The 30 minute countdown is scheduled on the server, which means the notification fires even if the tab gets closed, the laptop sleeps, or you switch to a different device halfway through. Label the timer ("oven roast", "chapter draft", "interval set 3") and the notification arrives with that label, so the context is obvious the moment it pings. Thirty minutes is also a popular alternative Pomodoro length: 30 minutes of focused work followed by a 5 minute break, repeated three times before a longer rest. If 30 feels long, drop to 25 or 15; if it feels short, jump to the 1 hour timer. The widget below accepts any whole number of minutes and the recurring-reminder option is one click away.

FAQ

Is 30 minutes a good cooking timer?
Yes — it is the standard window for a tray bake, a 30 minute roast, most braise simmer stages, and overnight oats setting. The notification arrives even if you have left the kitchen.
Can I use 30 minutes as a Pomodoro?
Many people prefer a 30/5 cadence over the classic 25/5 — slightly longer focus blocks with the same short breaks. Use the timer here and pair it with the 5 minute break timer between blocks.
Does it run when the tab is closed?
Yes. The 30 minute timer is scheduled server-side, so the Telegram, push, or email notification fires even if you close the page or lock the device.
Can I label the timer?
Yes. Type a short label like "oven roast" or "chapter draft" before pressing Start, and the notification you receive will include that label.
