YouTube Playlist Length Calculator

The YouTube Playlist Length Calculator is a free tool that calculates the total duration of YouTube playlists at various playback speeds (1x, 1.5x, 2x) by pasting the playlist URL. It provides details like total duration, number of videos, and average length. The tool optimizes YouTube Data API usage through request batching and handles large playlists with retry logic and stable pagination. It also features a refined mobile UI for better usability. Future updates may include exporting results, visual duration charts, and playlist comparison tools.
