February is a little longer this year thanks to 2020 being a leap year, but how is that calculated? Hint: It's not every four years! Meteorologist Steve Glazier explains in the video below. https://youtu.be/S_csshx2Xr8 Here are the basic guidelines for calculating a leap year:
  • Any year evenly divisible by 4, except if that year is also evenly divisible by 100, unless that year is also evenly divisible by 400
Confused? Be sure to watch the video above! Long story short, it does not take exactly 365 calendar days to make one orbit around our sun. It takes roughly 365.24 days and that extra time needs to be accounted for occasionally to make sure time is correct. That's why an extra day is added on to February every four years (mostly, according to the exceptions above). Enjoy the extra day this weekend!
