Time flies when you are busy, and a 940 second timer makes it visible. This free online countdown measures 15 minutes and 40 seconds precisely and lets you add your own text, an alarm and a final message.
When a 940 Second Timer Comes in Handy

- Screen-Time Limits: Agree on 15 minutes and 40 seconds of gaming or social media and let the alarm end the session instead of a discussion.
- Tidy-Up Challenge: Pick one room and see how much you can clean before the 940 seconds are over. It is a game the whole family can play.
- Classroom Activities: Teachers use a 940 second timer for reading time, group tasks or quiz rounds so everyone can see how much time is left.
- Cooking Rice: White rice usually simmers for 15 to 20 minutes, then rests briefly. A 940 second timer keeps the pot under control.
