LEAP year 411…

 

It’s a LEAP year… 

If you have yet to figure out what that means, The Y Life is leaping into your 411! 

About every four years there is this occurrence, known as a leap year … Y? Because there are 366 days in this year as opposed to a “common” year, which has 365. 

The Leap day normally occurs by adding an extra day to the 28 day month of February, because Leap years are needed to keep the modern day Gregorian calendar in alignment with the Earth’s revolving around the sun.

I know it sounds very scientific, right? But, it’s not that bad to understand, so here is how it breaks down… Since it takes our Earth about 365.242189 days – or in English… 365 days, 5 hours, 48 minutes, and 45 seconds – to circle once around the Sun, when we measure the tropical year from the March equinox. However, remember that Gregorian calendar we use, it has JUST 365 days in a year, WE HAVE NO CHOICE but to add an extra day, because if we didn’t add a leap day every four years, we would lose more than 5 hours off our calendar EVERY YEAR.. That’s a problem in the long run when after 100 years, our calendars would be off by just about 24 days!

CRAZY, right?! 

Remember Julius Caesar the Roman general? Well, he actually introduced the first leap year, just over 2000 years ago. It can be referred to as an intercalary year, because it contains that additional day to keep our lives synchronized with the astronomical year.

We are a society who has corrected our drift, by leaping forward a day in our calendar…  Similarly, the lunisolar Hebrew calendar, Adar Aleph, has a 13th lunar month added 7 times every 19 years, to the twelve lunar months we have come to know and love, to help avoid that the common calendar year drift through the seasons.

Y Fact… Wondering where the name “leap year” comes from????

So… While a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next, the day of the week in a leap year will also advance 2 days (from March on) due to the extra day added at the end of February (thus “leaping over” one of the days in the week)!!! 

Hope you have fun leaping forward this year!
