Leap Year
2024
Happy New Year!
2024 is a leap year, a year with an extra day to balance the calendar year with the solar or tropical year. An astronomical year lasts slightly less than 365 and one quarter days. Without an adjustment every four years our calendar would soon become out of synchronisation with the tropical year; in four years, it would be out by about one day and in 100 years it would be out by approximately 25 days.
Julius Caesar introduced the leap year in 45 BC. The Julian calendar ruled that any year number divisible by 4 would be a leap year but this resulted in many leap years. Pope Gregory XIII introduced the Gregorian calendar in 1582 to regulate this. The Julian calendar is 13 days behind the Gregorian calendar. It is still used in parts of the Eastern Orthodox Church as well as in Oriental Orthodoxy and by the Berbers in parts of North Africa.
Leap years occur every four years except for years that are divisible by 100 but not 400. 1900 was not a leap year, but 2000 was. For most of us, at least until 2100, if the last two numbers are divisible by 4, the year is a leap year.
The summer Olympics are held every four years, usually in a leap year. The 2020 Olympics were postponed for a year because of Covid. This year, Paris is hosting the summer Olympics from 26th July to 11th August.
The opening ceremony is usually entertaining though sometimes needs to be interpreted by the commentators, as the dance/drama sequences can be quite mystifying. I wonder why, when all the nations of the world can put aside their differences for two weeks to participate, such willingness to cooperate cannot translate to daily life. Of course, the athletes are competing for medals, not attempting to annex other people's lands. The spirit of apparent goodwill does not last. Consider the 1936 Olympics in Germany, which so incensed Hitler.
What state will our world be in by the summer of 2024?
