Another leap year is upon us. And while none of us was around back in Julius Caesar’s day, most people know that calendars back then had fewer days per year, which threw off the seasons over time. The 46 B.C. Julian calendar reformed the previous Roman one, bringing the number of days to 365 and standardizing one additional day – an “intercalary day” — every four years.
But adding a day every four years began to accumulate incrementally more time than the solar year. By the time Pope Gregory XIII was head of the Catholic Church in 1582, he was concerned about Easter becoming out of sync with the spring season. His calendar skipped leap year every 100 years – with the exception of every 400 years, when it is a leap year. This adjustment makes the Gregorian calendar as closely aligned with the solar year as possible.
The Gregorian calendar is the international standard today, although there are countries that do not use it – including Afghanistan, Ethiopia, and Iran.
If we did not work leap years into calendars periodically, the seasons would reverse every 730 years or so. Just imagine if the hemispheres’ climates swapped according to the calendar. Not that anyone would notice, since it would take about 24 generations to achieve.
The current generations have some decisions to make this year. Presidential elections are on the 2020 calendar, in the United States as well as in Bolivia, Burundi, Greece, Iceland, and Poland.
Meanwhile, we will enjoy an extra day at the end of February. And those born on February 29 can actually celebrate their birthdays on their birthdays, rather than on March 1 as is the norm. As we start the new leap year, here are two quotes from motivational presenter Tony Robbins, born on February 29, 1960:
“Success in life is the result of good judgment. Good judgment is usually the result of experience. Experience is usually the result of bad judgment.”
“Change is inevitable. Progress is optional.”
Here’s to a year of new experiences, and of learning, growth, health and happiness. Wishing you a Very Happy 2020!
