How set time calculator works
Put one track per line, starting with its length: 3:45, 1:02:03 or a plain number of seconds all work. Anything after the time is kept as the track name, so "3:45 Nightdrive" lines read naturally. The calculator parses every line, rejects the ones it cannot read, and adds the lengths up to the total playtime of the set.
Transitions are where real sets diverge from bare tracklists. Set a gap in seconds — 5 s between tracks is a common DJ pace — and the tool adds it after every track except the last, so a 12-track set with 5-second gaps carries 55 seconds of transitions. The result panel splits playtime and gap time so you can see both, plus the average track length and the longest and shortest track.
The per-track table shows a running clock: each track’s start time and its share of the set. That turns the maths into planning — if the venue gave you a 60-minute slot and you are at 63:40, drop the track whose share and flow matter least; if the headline is waiting, you know exactly which cut gets you to the stage on time. Everything is computed in your browser, so unfinished setlists stay on your machine.
