Set the timer to 19 hours

How to use the online timer

A long-haul flight of 19 hours goes faster when you break it into chunks instead of watching the in-flight map crawl across the screen. Set the timer for a stretch of reading, sleeping, or a movie, and let it mark the end of that chunk rather than checking your watch every twenty minutes. It won't make the flight land any sooner, but it makes the hours feel like they're moving somewhere.

It runs the moment you hit Start, no extra steps needed before the numbers begin moving. Because everything happens inside this browser tab, it needs to remain open while the clock runs; switching tabs is fine, but closing the page or turning off your screen partway through will stop the countdown. A sound marks the finish, so you'll know the moment it's done without having to watch it count down.

A mechanical timer needs to be wound and a phone timer needs the phone unlocked, but this one just needs the page you already have open. It sits inside your browser, ready whenever you are, and it's the same tool whether you're on a laptop or a tablet in the kitchen. Free, with nothing to install or sign into, it's built to get out of your way and count. People type this as set timer 19 hours or timer for 19 hours; both land here and start the same count.

Common questions

Does the timer make a sound when it finishes?

Yes, an alarm plays once it reaches zero, provided your device's volume is turned up and the tab hasn't been muted.

Can I pause the timer partway through?

Yes, pause and resume are both available, so you can stop the count if you're interrupted and pick up again exactly where you left off.

Can I set a custom time instead of the preset?

Yes, most pages let you adjust the minutes and seconds directly, so you're not limited to the exact length shown in the page title.

Does the timer work without an internet connection?

The page needs to load once, but the countdown itself runs locally in your browser, so a dropped connection partway through won't stop it.
