Aunt Wiki says, "A calendar year has 365 days. But because one tropical year is 365.24219 days long, one day must deviate. This happens once every four years, and that's when an extra day is inserted often says a leap day (see the Julian calendar), bringing the value to 365.25 days a year, which is not an accurate enough length of a tropical year, a shift of 7.81 days in a thousand years, which is more than the actual number. the calendar specified that years divisible by 100 are transferable only if they are divisible by 400. For example, the years 1600, 2000, etc. were transferable. The years 1700, 1800, 1900, 2100, etc. are not transferable. This achieves an average value of 365.2425 days per year. "The deviation of the Gregorian calendar, therefore, is 31 days, which will last for 100,000 years." The story of Maruška, which her stepmother drove away on the ********* holidays for strawberries, will eventually have a real basis ... and imagine ********* and New Year's Eve at the swimming pool. How would skiers, sledders and 12 fairy-tale moons sitting around the fire come to this ??
