Playlist Duration Calculator

How to use

1. 1Paste your playlist, one item per line. Song or video titles can include the duration anywhere on the line: 'Bohemian Rhapsody 5:55', 'Ep 412 (1:08:14)', or 'Lecture 1h 23m'.
2. 2Read the total runtime at the top of the result panel. It is shown in H:MM:SS, as a long phrase, and as decimal hours, minutes, and seconds.
3. 3Switch the playback speed for podcasts or lectures (1.25x to 2x). The adjusted total updates in real time.
4. 4Set a break-between-items value to add a fixed gap (in seconds) between consecutive items for transitions or rest periods.
5. 5Comment a line with # or // to keep it visible without counting it. Lines with no detectable duration are flagged in the per-line table.
6. 6Use Copy report to grab the total, per-item rows, and every setting as plain text, or click an example button to load a starting list.

About this tool

Playlist Duration Calculator sums the runtime of a list of songs, podcast episodes, videos, lectures, lessons, or workout intervals in your browser. Paste one item per line and the parser reads any common time format that appears anywhere on the line: M:SS like 3:45, H:MM:SS like 1:23:45, leading-zero forms like 01:23:45, and unit styles like 90s, 1m 30s, 2h 15m, 1.5h, or 90 min. Times wrapped in parentheses or square brackets (Song Name (3:45) or Title [12:34]) are recognized, as are numbered prefixes like 01., #5, or Ep 412 so the row counter you copied from Spotify, Apple Music, a podcast app, YouTube Music, a SoundCloud playlist, a Bandcamp album, a Notion lecture log, or a DJ set list does not break the time pickup. Each line shows a detected title and duration in a per-line breakdown so you can audit what was counted, what was skipped (lines that start with # or // are treated as comments), and which lines had no recognizable time so you can fix or ignore them. The totalizer reports the full runtime in H:MM:SS clock form and as a long phrase like '2 hours, 15 minutes, 30 seconds', plus decimal hours, decimal minutes, and total seconds for spreadsheets. A playback-speed selector recomputes the listening time at 0.5x through 3x, useful for podcasts at 1.25x to 2x where the on-platform length is not the time you actually spend. A break-between-items field adds a fixed gap between consecutive items, which is how DJs estimate set length with transitions, classroom planners build agendas with stretch breaks, fitness coaches schedule intervals with rest, and event planners pad set changes. Stats like longest item, shortest item, and average runtime help DJs balance a set, podcast producers spot outlier episodes, and teachers split a lesson plan. Everything runs locally in your browser, so the playlist you paste in is never uploaded. Useful for music producers, DJs, choir directors, podcasters, podcast listeners, YouTubers planning a binge session, teachers building a lecture queue, fitness instructors, dance coaches, audiobook listeners, event planners, anyone padding a presentation runtime, and any time you need the total time of a list of timed items without doing the arithmetic by hand.
