So, the Julian calendar introduced an error of one day every 128 years, which meant that every 128 years the tropical year shifts one day backward with respect to the calendar. 0078 of a day (about 11 minutes and 14 seconds) longer than the tropical year. The Julian calendar worked so well at first that many countries adopted it. Then, to honor his contribution to timekeeping, Caesar later renamed the fifth month (formerly known as Quintilis) after himself (July). (Note, this explains why leap years are also known as intercalary years.) The end result was a year that was fifteen months and 445 days long, and was nicknamed Annus Confusionus, “Year of Confusion.” Two other months ( Intercalaris Prior and Intercalaris Posterior) were added after November. One month was added between February and March. Caesar divided the ninety extra days into three temporary months. Initially, in order to make a proper transition from the Roman calendar (which had 355 days and which was basically a lunar calendar) to the Julian calendar and get the months and various feasts and holidays back into their normal seasons, ninety extra days were inserted into the year 46 BC. At that time, February was the last month of the year. This new “Julian” calendar was used throughout the Roman Empire and by various Christian churches. So to account for that residual quarter of a day, an extra day-known as leap day-was added to the calendar every four years.

Leap Day is an artifact that dates back to 46 BC when Julius Caesar took the advice of the learned astronomer, Sosigenes of Alexandria, who knew from Egyptian experience that it took 365.25 days for the Earth to circle once around the Sun (known as a tropical year or solar year).

So, if your birthday fell on a Wednesday last year, in a leap year it “leaps” over Thursday and lands on Friday.
#Leap year list plus
A leap year is comprised of 52 weeks plus two days. However, a leap year changes this scenario. This extra day means that if your birthday falls on a Tuesday in one common year, it will fall on a Wednesday the next common year, and so on. Why Do We Call It A “Leap” Year?Ĭommon (non-leap) years are composed of exactly 52 weeks, plus one day. Unlike the calendar, which organizes each year into a neat 365 days, it actually takes the Earth 365.242199 days-or 365 days, 5 hours, 48 minutes, and 46 seconds-to circle once around the Sun. The reason for the extra day during some years has to do with our need to keep our modern-day Gregorian Calendar in alignment with the Earth’s revolutions around the Sun. The leap year system makes the calendar coincide with the cycle of the seasons.The next leap year will occur in 2024. So, any year divisible by four is a leap year! (for this centuty). So, we can surely say that: "until 2096, if we want to know if a given year is leap or not, we just need to check if thath year is or is not divisible by 4. For this century, is not necessary to check the other conditions. The year being divisible by 4 is a necessary condition, but not sufficient for a year to be leap, but for this century, we may consider sufficient until the year 2098.
