What this calculator does
The TV Series Duration Calculator adds up the total runtime of a TV show from its basic structure — how many seasons it has, how many episodes are in each season, and how long each episode runs — and estimates how many days it would take to watch the whole series at your own pace.
How the calculation works
Total episodes is seasons multiplied by episodes per season. Total runtime multiplies that episode count by the average episode length, converted from minutes to hours (and, for reference, to a continuous 24-hour day count). Days to finish divides the total runtime by how many hours a day you plan to watch.
This is a straightforward runtime estimate for planning purposes; real shows often vary episode length season to season, so treat the result as an approximation.
