YouTube Watch Time Calculator

A watch time calculator adds up the length of a list of separate YouTube videos. It's for everything that isn't a single playlist: a Watch Later backlog, talks a friend recommended, videos a teacher assigned from different channels, or a set of Shorts.

Paste up to 500 links and it looks up each video's real duration, counts duplicates once, and lists anything that isn't a video. You get the total at normal speed and at 1.25x to 2x, plus how many days it takes at your own daily pace. The result's address holds the video IDs, so you can bookmark the list or send it to someone and they'll see the same totals.

Watch Later lists, a few lectures from different channels, the videos a teacher assigned, or a handful of talks someone sent you: none of them are one playlist, so YouTube can't tell you how long they take together. Paste the links here and you get the total, the time at faster speeds, and how many days it takes at your pace.

Lengths come from the YouTube Data API, the same numbers YouTube shows on each video. Private and deleted videos can't be read and are left out of the total. The result's link holds the video IDs, so you can bookmark it or send it to someone.
