Neil deGrasse Tyson explains leap years on StarTalk, twice

Happy Leap Year Day! Once again, I'm sharing the science and history of the day with Neil deGrasse Explains Why We Have Leap Days on StarTalk.

What’s going on with Leap Year? Neil deGrasse Tyson and comedian Chuck Nice explain why we sometimes have that extra day in February.

Learn about the rotation and orbit of the Earth and how our orbit isn’t exactly 365 days. What is the difference between the Gregorian and Julian Calendar? We take a trip back to 1582 to find out why The Pope took out 10 days of October. Plus, find out why 2000 was such a special leap year.
Neil and Chuck laughing about a new year observance that changes its hour and sometimes even day every year reminds me that celebrations of Nowruz follow the Vernal Equinox around the clock and occasionally the calendar instead of being fixed on March 21, which is why I celebrate on International Day of Nowruz instead.

By the way, as Neil alluded to, this is not the first time he's explained leap years on StarTalk. I found The Leap Year as Explained by Neil deGrasse Tyson | StarTalk on National Geographic's YouTube channel from 2016.

Neil deGrasse Tyson explains the logic behind the leap year, with a brief history in calendars as well.
It's still the same basic story, so I can tell he's been telling it for a long time, but in fairness, Chuck wasn't there, so this year's video was the first time he dedicated an entire episode with Chuck present.

This concludes February's blogging. Stay tuned for the first post of March, when I plan on celebrating a bunch of holidays, including this blog's 13th birthday. My blog will become a teenager!
