About this site
This site exists because playlist length is one of those small questions that becomes annoying fast. A course playlist says it has 87 videos. A creator has a long series. A saved watch queue looks manageable until you realize every video is twenty minutes. The calculator is meant to answer the practical question first: how much time is this going to take?
Why keep it focused?
There are many things a YouTube utility site can do, but this one starts with the calculator because that is the job people came for. Paste a playlist, get the duration, compare playback speeds, and decide how to plan the time. The page is deliberately not packed with unrelated tools, popups, or long detours before the input box.
Who it is for
Students use it before starting a lecture playlist. People learning a skill use it to see whether a tutorial series fits into a weekend. Casual viewers use it to compare a few saved playlists. It is also useful for anyone who watches at 1.5x or 2x and wants a realistic estimate instead of guessing from the number of videos.
What the calculator tries to do well
It accepts common YouTube URL formats, supports multi-line input, handles single videos as well as playlists, and lets you calculate only part of a playlist with range controls. The result shows normal duration, faster playback estimates, counted videos, unavailable videos, and a daily watch-time planner. That is the core experience.
What it does not pretend to be
It is not YouTube. It cannot see private videos that YouTube does not expose through the API. It cannot make deleted videos readable. It cannot guarantee that a playlist will stay the same tomorrow. The goal is to give a clear, honest watch-time estimate from the data that is available right now.
The site is independent and maintained as a simple planning tool. If you find a link format that should work, or if a result is confusing, the contact page is the best place to send details.
