2020 is one of those oddities that occurs (almost) every four years: a leap year. Leap years were first created to account for the mismatch of timing between the Earth making one revolution on is own, or a day, and how long it takes to travel around the sun, which is one year. The amount of time it actually takes the Earth to revolve around the sun is 365.2422 days (if we’re rounding). That means over the course of four years, there actually adds an extra day we haven’t accounted for if we only make a 365-day calendar.

Hence the leap year, which gives us the extra day of February 29.

I love leap years because it’s like we get a little added bonus. Sort of like how there are some added bonuses prior to the 2020 Annual ACDIS Conference that you might not know about.
