Star Trek has existed across 60 years, dozens of seasons, and hundreds of hours but to watch all of it is a true test of will.
Star Trek has been around for so long that it’s actually quite surprising how much content there is for the franchise. Honestly, there is something for everyone. You don’t always get that in a franchise. Not every fan is happy about that, either, which is fine. Not everyone has to like everything.
All in all, there are nine series of Star Trek, 13 movies, and hundreds and hundreds of hours of content to watch. So many hours that the folks at CBR.com broke down just how many days it would take to watch the entire universe of Star Trek offerings; which don’t include fan-made content.
"All 13 Star Trek films have a combined total of 25 hours and 17 minutes, or just over a full day. Every single television series, both currently airing and retired, total up to 626 hours and 31 minutes, or just over 26 days. Every series and movie combined totals to 651 hours and 48 minutes, meaning it will take over 27 days to watch them all uninterrupted. Obviously watching them all consecutively is impossible, but realistically watching everything Star Trek could take less than half a year. For those who believe this beloved universe is worth investing over 39,000 minutes of life, it’s time to boldly go where only true diehard Trekkies have gone before."
Except, as noted, it’s not possible to watch all 651 hours and 48 minutes of Star Trek content. So if that’s the case, how long would it actually take to watch everything? Well, the average person watches four hours of television a day. That means if you only watch four hours of content a day, it would take you 163 days to watch everything.
That’s five straight months of nothing but the adventures of Starfleet and friends.
Again, though, that doesn’t factor in the hundreds of hours of fan-made content that’s non-cannon. Nor does it bring in the extended universe of content like books and video games. Realistically, you’re looking at something far longer than a month of non-stop Trek or even five months of interrupted viewing.
You’re more likely looking at an entire year’s worth of content, if not more to get through every Star Trek story that there’s ever been.
