> The TV series duration calculator works out how long it takes to watch a whole series – total episodes and hours – and how many days or weeks to finish it at your daily viewing time.

## Inputs

- Episode length (min)
- Episodes per season
- Seasons
- Viewing time per day (h)

## Results

- Total episodes
- Total watching time
- Days to finish
- Weeks to finish

## Formula

```
Total episodes = episodes per season × seasons
Total time = episodes × episode length
Days to finish = total time ÷ viewing time per day
```

## Explanation

Binge-watching a long series takes more time than you might think: a show with nine seasons of 22 half-hour episodes takes over 70 hours. Planning how much you watch each day tells you when you will reach the finale.

### How to use the TV Series Duration Calculator

### Tips

- Results are estimates meant for planning and fun – adjust the inputs to match your situation.
- Everything runs in your browser, so you can try as many variations as you like.
- Share the result link with friends so everyone sees the same numbers.
- For safety-related hobbies (hammocks, balloons, tents), follow the manufacturer's limits.

### Common mistakes to avoid

### What each result means

- **Total episodes** = [Episodes per season]×[Seasons]
- **Total watching time** = [Total episodes]×[Episode length]÷60
- **Days to finish** = ceil([Total watching time]÷[Viewing time per day] - 0.000001)
- **Weeks to finish** = [Days to finish]÷7

## Worked example

Inputs — Episode length: 45 min; Episodes per season: 10; Seasons: 5; Viewing time per day: 2 h.

Results — Total episodes = 50; **Total watching time = 37 h 30 min**; Days to finish = 19; Weeks to finish = 2.7.

## FAQ

**How long does it take to watch a whole series?**
Multiply episodes by their length: 50 episodes of 45 minutes is 37.5 hours.

**How long would a binge take non-stop?**
Total hours ÷ 24 – a 37.5-hour series is about 1.6 days without sleep (not recommended!).

**Do streaming episodes include ads?**
Usually not, which makes them 20–25% shorter than broadcast slots.

**What formula does the TV Series Duration Calculator use?**
Total episodes = episodes per season × seasons.
