What is yttime?
yttime is a free YouTube Playlist Length Calculator that tells you exactly how long any playlist takes to watch. Whether you need to plan study sessions around a lecture series, schedule time for an online course, or simply find out how long a music compilation runs, this tool gives you an instant answer. Enter one or more playlist links and get the total YouTube playlist time broken down by playback speed — 1x, 1.25x, 1.5x, 1.75x, or any custom rate you prefer.
Unlike manually scrolling through every video to add up durations, this YouTube playlist length calculator does the math for you in seconds. It also handles partial playlists: set a start and end range to calculate the duration of only the videos you actually plan to watch.
How to Calculate YouTube Playlist Duration
Use this online playlist calculator to convert playlist length into real watch-time estimates in just a few steps:
- Paste playlist links or IDs — Add one or many YouTube playlist URLs — separated by a new line, comma, or space.
- Set an optional range — Apply a Start and End range to newly added playlists. Great for large courses where you only need a specific section.
- Click Analyze — The tool fetches every video, sums the durations, and builds a comparison table in seconds.
- Fine-tune per playlist — Adjust the Start/End range on individual rows to measure exactly the videos you care about.
- Compare speeds instantly — See totals at 1x, 1.25x, 1.5x, 1.75x, and any custom playback speed you set.
Note: totals can change if videos become unavailable (private/deleted/region-blocked) or if a playlist is updated after analysis.
