And how did leap day come about?
Way back in 46 B.C., Julius Caesar realized the calendar they were following wasn't working. So he consulted with an astronomer. Together they realized what the Egyptians had already discovered -- that we needed that extra day every four years to stay on track. So he instituted the Julian calendar. But even that wasn't quite right._____
The solar year is actually only .242 days longer than the calendar year, and not an even .25. So when we add a full day every four years, we're actually left with a surplus of roughly 11 minutes every year. And that can start to add up.
So finally in 1582, Pope Gregory XVII fixed the glitch and instituted the Gregorian calendar which we still follow today.
How is it different? We'll let Michio Kaku explain:
"The 11 minutes difference in one year's rotation builds up. And that's why the pope had to intervene and say we have to tweak the Julian calendar one more time," Kaku said. "So for example, in the year 1600, that is divisible by 400, there was a leap year. But in 1700, 1800, 1900 -- nope, no leap year. And then the year 2000 there was again a leap year."
Unlike Trump, however, Rubio and Cruz are far less electable.
