Movie Marathon Calculator
Movie Marathon Calculator: Know When You'll Actually Finish
Stacking up several movies back to back can add up to a much longer night than you'd expect. This calculator totals the runtimes and, if you give it a start time, tells you exactly when the marathon will wrap up.
The Formula
Total Minutes = sum of all movie runtimes
Worked Example
Three movies running 120, 95, and 142 minutes, starting at 18:00.
Total = 120+95+142 = 357 minutes = 5h 57m, ending at 23:57
How to Use This Calculator
- Enter the runtime in minutes for each movie in your lineup (up to 5).
- Optionally enter your marathon start time to see the finish time.
- Click Calculate to get the total runtime and end time.
