To make a YouTube video start at a specific time, add &t=X (where X is seconds) or &t=YmZs (e.g., 1m30s) to the end of the URL; for embedding or sharing, use the share button's "Start at" checkbox or manually edit the URL/embed code with start=X&end=Y for both start and stop points, or use YouTube Studio for creator-side end screens/trimming.

The Sleep Timer is available on YouTube's mobile apps for both iOS and Android and on desktop via the browser. It's also part of the YouTube Music app, with some slight differences in the available timing options.
Energy Use Overnight or Long Hours
Leaving your system in sleep mode overnight can lead to significant battery or power drain, depending on the device type.
Click your profile picture . Click Appearance . Select "Dark theme" to use the dark theme setting. Turn on Light theme or Use device theme.
Go to the video you'd like to watch. Tap Settings in the player. Tap Sleep timer . Select how long you want the timer to run before your video automatically pauses.
When you set a sleep timer, you can fall asleep watching videos and have them automatically pause after a certain time. If you want to be reminded when it's time to go to bed, you can set a bedtime reminder.
If you prefer not to use an extension, you can manually create a loop by adjusting the video's URL. For example, adding the timestamp parameters to the URL (&start=X&end=Y) where X is the start time and Y is the end time, can loop the specific section by refreshing the page repeatedly.
