YouTube Playlist Watch Time Calculator lets you instantly calculate the total duration of any YouTube playlist.
It works directly on YouTube playlist and watch pages, showing the total watch time at playback speeds ranging from 0.25x up to 4x, including common speeds like 1x, 1.25x, 1.5x, and 2x.
The extension runs entirely locally in your browser, does not collect or transmit any personal data, and stores only user preferences such as theme and language using browser storage.
