TV Series Duration Calculator

Multiply the number of seasons by the number of episodes per season to get the total episode count. Then multiply that by the average episode runtime in minutes. For example, a show with 5 seasons, 13 episodes each, and 45-minute episodes totals 2,925 minutes (or about 48.75 hours).

Divide the total watch time in hours by how many hours per day you plan to watch. If a series is 48 hours long and you watch 2 hours a day, it would take 24 days to finish. Our calculator handles this automatically once you enter your daily watch time.

The Simpsons has over 30 seasons and 700+ episodes, each roughly 22 minutes long. That adds up to around 260+ hours of content — more than 10 continuous days. At 2 hours of watching per day, it would take over 130 days to finish.

These runtimes are tied to traditional broadcast TV slots. A 30-minute slot leaves roughly 22 minutes after ads, while a 60-minute slot yields about 44–45 minutes of actual content. Streaming shows are now less constrained by these conventions, but many still follow them out of habit or format convention.

This calculator uses an average episode count across all seasons for simplicity. If seasons vary significantly, you can run multiple calculations and add the results, or use the average episodes per season as a close approximation.

For the most accurate result, use the average episode duration across all seasons. If a show has earlier shorter episodes and later longer ones, adding up the runtimes and dividing by total episodes gives you a good average to use as input.

The total watch time in hours is divided by the number of hours you watch per day. This gives a realistic estimate of calendar days needed at your chosen pace, assuming you watch every day without breaks.

Yes — just run the calculator separately for each show and compare the total hours or days-to-finish figures. It's a great way to decide which series to start based on how much time you have available.
