Google Timer

The desktop Google Search has a cool feature: search for [set timer for 5 minutes] and you'll see this interactive timer box. You can stop the timer, reset it and Google even has a notification sound you can disable.

Here's a video for a 15 seconds timer:

You can search for [set timer for 30 seconds], [set timer for 10 minutes and 10 seconds], [set timer for an hour and a half]. You can also use shorter queries: [timer for 30 seconds], [timer 30 seconds], [timer 30 sec], [timer 23 hours 59 min 59 sec].

If you close the search page, Google shows a warning: "Leaving this page will stop your timer".

Click "reset" and it will start again. Click the volume icon to mute sound notifications. Click the timer and you can edit it (press Enter when finished):

You can also search for [timer 2pm], [timer 5:30], [timer 2pm tomorrow], [timer 2pm Thursday], but it doesn't work well everywhere. In Europe it uses GMT time, not the local time.
