Playlist durations are calculated from public metadata returned by the YouTube Data API. We do not ask users for their own API key.
Private, deleted, unavailable, dynamic, and account-specific playlist items may be skipped or rejected because they cannot be read reliably.
The calculator works from public playlist URLs. It does not connect to your YouTube account or read your private library.
The site is maintained for students, teachers, creators, and listeners who need realistic watch or listening time before they start.
Playlist Length Calc is maintained as an independent playlist planning tool. The goal is simple: make playlist time visible before someone commits to a course, study plan, commute playlist, workout mix, or long listening queue.
We keep the calculator free to use, document known limitations, and prioritize fixes that improve calculation reliability, page speed, accessibility, and transparent search snippets.
