Calculate a range or the videos you have left
Use original video numbers for a range or a remaining calculation without losing track of missing entries.
Updated September 8, 2026 · PlaylistLengths product guide
Choose what you mean by remaining
If you have finished video 12, select What I have left and enter 12. Calculation starts with video 13. If you still need to watch video 12, choose Include that video.
This setting works at whole-video boundaries. It does not inspect the position of a video playing in YouTube or read your account history. For an exact resume point in a generated schedule, use the timestamp link in that schedule.
Both range endpoints count
A specific range of 4–7 contains positions 4, 5, 6 and 7. Selecting 7–7 is valid and calculates a single original entry. If a position is unavailable, it still belongs to the range.
For example, suppose videos 4, 5 and 6 have durations of 120 seconds, unavailable and 180 seconds. Range 5–6 contains two entries and 180 counted seconds. The unknown duration is shown as excluded, not silently removed from the numbering.
Original numbers stay put
Videos keep their original YouTube positions everywhere — in the table, in ranges and in schedules. This makes a saved range meaningful: “start at video 31” refers to the same entry when you come back.
Finishing the last known entry in a complete playlist returns zero remaining time. An incomplete playlist cannot establish that there are no more videos after the loaded segment.
