What is this calculator?
Planning a back-to-back film session? This calculator turns your line-up into real time. Enter how many movies you want to watch, roughly how long each one runs and how much of a break you take between them, and it returns the total marathon length in hours and days, plus a rough count of the meals you would need along the way.
How does it work?
Total viewing time is the number of movies multiplied by their average length, and the breaks are added on for every gap between films. That total is shown in hours and converted to days by dividing by 24. Meals are estimated at roughly one every five hours of marathon time.
Frequently asked questions
How long is a typical movie marathon?+
Six films at two hours each with short breaks lands around 13.3 hours, which is most of a day.
Why does the break time matter?+
Breaks add up fast. Fifteen minutes between ten films is another two and a half hours on top of the running time.
How are meals estimated?+
Roughly one meal for every five hours of marathon, which keeps energy up without pausing constantly.
Should I plan for sleep?+
Anything past about twelve hours realistically needs a sleep break, so treat long totals as a multi-day plan.
Does it include credits and trailers?+
Only if you build them into the average movie length. Add ten minutes per film if you always watch the credits.
