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
Formula
Total episodes = episodes per season × seasonsTotal time = episodes × episode lengthDays to finish = total time ÷ viewing time per dayWorked 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.
