What Time Is The End of The Daylight?

What time is the end of the daylight? The sun is expected to die in roughly 5 billion years. But humans—provided we survive any number of ecological, nuclear, or alien-based disasters—are only expected to last about another 1 billion years on Earth.

So technically the “daylight” will be over for humanity in 1 billion years, which is again, predicated upon the absurd assumption that we make it that long anyway.

But if we define the “daylight” as the existence of the sun, that will be around for much longer. It’ll burn for another 5 billion years before it will have fully exploded into a red giant star, expanding as far as Mars and destroying everything humans have ever touched. But don’t worry, you and everyone you’ve ever known or cared about in any way will be long dead by then.


Five billion years can be tough to visualize, so to put that in perspective, that’s 157,700,000,000,000,000 seconds.

Also, it’s Daylight Saving Time at 2:00am on Sunday, March 13th so don’t forget to set your clocks ahead one hour. Fall back, spring forward!
