Set the timer to 229 minutes

How to use the online timer

Keeping track of a 229 minutes fasting or eating window is easier with a timer running than trying to remember what time you started. Set it the moment your window opens or closes, check back whenever you like without resetting anything, and let it count down in a browser tab you can leave open on your phone or computer. No app, no account, just the number you need.

Hit Start whenever you're ready and the timer runs on its own from there, no further clicking required until it finishes. It only counts while the tab stays open, so leave it running in the background rather than closing the browser or navigating away if you need the time to stay accurate. Once it reaches zero, an alarm sound lets you know without you having to keep checking the page.

A phone timer works fine until a call comes in or a notification steals the screen at the worst moment. Running it in a browser tab keeps it separate from all that, ticking away quietly in the background of your computer or phone without competing for attention until it's done. There's nothing to install and nothing to sign up for, just a page that does one job well. If you would rather say put a timer on for 229 minutes, that works too — press Start and the page does the rest.
