What would happen if we removed leap years ? Consequences worse than you imagine

This Thursday is February 29. What would be the consequences of not having such a day every four years??

This Thursday will be February 29, so it is a leap year. Every four years, the year lasts one day longer, or 366 days. 2024 is a leap year as will be 2028, 2032 , 2036, 2040… Why are they so necessary ? To understand, we have to go back to ancient Rome. At the time, the calendar lasted 355 days because it was based on the cycles of the Moon and not on the cycles of the Moon. those of the Sun. This being said, a problem quickly arose: this calendar corresponded less and less to the seasons. An additional month was then added. added every two years at the end of the year.

It was not until 45 BC that Julius Caesar introduced the solar calendar. As with the lunar, he again noticed a shift but this time it was less significant. This is why every four years, an additional day has been added. added in February. The Earth goes around the sun in 365 and a quarter days, every four years, one more day   This was necessary to take into account this additional quarter.

This organization of the calendar remained for a long time but has nevertheless undergone some modifications. Pope Gregory XIII notably signed an ordinance in 1582 to remove leap years from centenaries, years divisible by 100 unless they were divisible by 400. This was # 39;an adjustment after the discovery that the Earth did not take exactly 365.25 days to go around the Sun but 365.24219 days. This is how the company was born. the Gregorian calendar with which we still operate today.

What would be the consequences of the absence of leap years ? Every year, 5 hours,& ;nbsp;48 minutes and a few seconds would be lost compared to the Earth's tour around the Sun and above all they would never be made up for. The shift would end up being very significant. The concordance between the seasons and the calendar would gradually disappear. Thus, the winter weather might not correspond to the weather. the period between December and February and in a few hundred years, July would occur in winter. Visions of celestial events like the solstices and equinoxes could also become difficult. And let's think about agriculture: this could endanger the harvests. It would therefore be very difficult to do without it.
