I find it absolutely fascinating and inspiring that our solar system is so constant that all it takes is one adjustment day every four years to keep things synchronized. There must be something Divine about that.
Here is a sampling of writings on Leap Year worth checking out, and I leave the best for last.
According to timeanddate.com, Leap Years are needed to keep our calendar in alignment with the Earth’s revolutions around the sun. It doesn’t take 365 days to circle the sun, it takes 365.242199 days – or 365 days, 5 hours, 48 minutes, and 46 seconds. So if we didn’t add a day on February 29 nearly every 4 years, we would lose almost six hours off our calendar every year, then after 100 years, our calendar would be off by 24 days.
There are various other calendars that have Leap Years. The Chinese Calendar has 13 months with a leap month added about every 3 years. The Jewish calendar has 13 months in a leap year. There are 29 or 30 days in each month in a Jewish leap year, which has 383, 384, or 385 days. A leap year is referred to in Hebrew as Shanah Me’uberet, or a pregnant year.
The Iranian calendar is slightly more accurate than the Gregorian calendar. Compared with the Gregorian calendar, which errors by one day in about every 3226 years, the Iranian calendar needs a one-day correction in about every 141,000 years. The Islamic Hijri calendar has a 11 leap years in a 30-year cycle. An extra day is added to the last month of the year during the Islamic leap year.
The Hindu calendar includes an extra month, once every three years or four times in 11 years. A leap year in the Ethiopian calendar is similar to the Gregorian calendar in which an extra day is added to the last month of the year every 4 years.
In a departure from calendars, let’s look at Leap Day 2012 at Disneyland: for the first time ever, Disneyland stayed open for 24 HOURS today!
To close with the best: First, an exploration of the various calculations used to define a year. Scroll down about 2/3 of the way.
And my favorite, a fascinating point of view that our calendar has actually always been in place since Genesis.
…Thought provoking perspectives on time…space…and eternity.
