The short answer
A 30 minute timer counts down 1,800 seconds and rings at zero. Press Start above; it keeps time in a background tab and after a reload. Thirty minutes a day, five days a week, is the CDC's example of reaching 150 minutes of moderate activity, so it suits a brisk walk, a workout or cooking dinner.
What fits in 30 minutes?
Half an hour is a real session. These are the habits people most often try to fit into it.
- A brisk walk. Thirty minutes, five days a week, is the CDC's example of meeting the 150-minute weekly goal. Build up with the 30-day walking habit plan.
- Cook dinner at home. A simple meal from scratch in half an hour. Tips in how to cook at home more often.
- A 25 + 5 study session. One Pomodoro and its break fit exactly into 30 minutes.
- Read for half an hour. Enough for a chapter or two of most novels, and a quiet end to the day.
- A whole-home reset. Ten minutes each for the kitchen, the living room and the bedroom. Everyone at home can help.
How to use the 30 minute timer
- Press Start. The timer is already set to 30 minutes. The space bar starts and pauses it too.
- Need a different time? Type it in the box, such as 7, 7m 30s or 7:30, and press Set. Or tap another preset.
- Make it big. Full screen (or F) shows only the countdown. Kids view shows a big colored disk that shrinks as time runs out.
- When it rings, press Stop alarm or the space bar. Restart runs the same 30 minutes again; +1 min snoozes for a minute.
The timer saves the moment it will end on your device, so it stays accurate in a background tab and after a reload, and the time left shows in the tab title. The page has to stay open for the alarm to play.
Frequently asked questions
Is 30 minutes of walking a day enough?
For the aerobic part of the CDC guideline, 30 minutes of brisk walking on five days a week reaches the 150 minutes of moderate activity adults need. The CDC also recommends muscle-strengthening activity on two days a week.
Can I split 30 minutes into shorter blocks?
Yes. The CDC says you can spread activity across the week and break it into smaller chunks, so three 10-minute walks count too. Use the 10 minute timer for each one.
Does the 30 minute timer keep counting if I switch tabs?
Yes. It saves when the timer will end, so switching tabs, locking a laptop or reloading keeps the right time. The time left also shows in the tab title.
