Today Is The Longest Day EVER
Sounds like that means you're having a bad day, right? Not exactly! Scientifically today is the longest day of 2015 and it has nothing to do with how many hours of sunlight there are.
This afternoon at 6 PM, the Coordinated Universal Time will add a leap second so that it matches the atomic clock that they made way back in the 1950s. It has something to with the earth rotating at an inconsistent speed. Adding a leap second to make up for it makes clocks more accurate and is supposedly super important to keeping GPS devices on point while measuring distances and locations.
That's too much science stuff for me. Someone tell me when we're going to permanently add an extra hour to the day!
