Leap and non-leap years. Interesting facts and signs about leap year

2016 is a leap year with 366 days instead of the usual 365. Leap year was proposed to synchronize calendars. Did you know that not every 4th year is a leap year?Why is a leap year considered unlucky, and what signs are associated with it?Here are a few facts you may not know about leap year.

What does leap year mean?

1 . A leap year is a year that has 366 days rather than the usual 365. An additional day in a leap year is added in February - February 29 (leap day).

An additional day in a leap year is necessary because a full revolution around the Sun takes a little more than 365 days, or rather 365 days, 5 hours, 48 ​​minutes and 46 seconds.

People once followed a 355-day calendar with an additional 22-day month every two years. But in 45 BC. Julius Caesar, together with the astronomer Sosigenes, decided to simplify the situation, and the Julian 365-day calendar was developed, with an extra day every 4 years to compensate for the extra hours.

This day was added in February as it was once last months in the Roman calendar.

2 . This system was supplemented by Pope Gregory XIII (who introduced the Gregorian calendar), who coined the term "leap year" and declared that year, multiple of 4 and multiple of 400, but not multiple of 100, is a leap year.

So, according to the Gregorian calendar, 2000 was a leap year, but 1700, 1800 and 1900 were not.

What are leap years in the 20th and 21st centuries?

1904, 1908, 1912, 1916, 1920, 1924, 1928, 1932, 1936, 1940, 1944, 1948, 1952, 1956, 1960, 1964, 1968, 1972, 1976, 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, 2048, 2052, 2056, 2060, 2064, 2068, 2072, 2076, 2080, 2084, 2088, 2092, 2096

Why on earth is 1900 not a leap year? A leap year occurs every 4 years, i.e. If it is divisible by 4, it is a leap year. And no more divisions by 100 or 400 are needed.

It’s normal to ask questions, but before you assert anything, study the hardware. The Earth revolves around the sun in 365 days 5 hours 48 minutes 46 seconds. As you can see, the remainder is not exactly 6 hours, but 11 minutes 14 seconds less. This means that by making a leap year we add extra time. Somewhere over 128 years, extra days accumulate. Therefore, every 128 years in one of the 4-year cycles there is no need to make a leap year in order to get rid of these extra days. But to simplify things, every 100th year is not a leap year. Is the idea clear? Fine. What then should we do next, since an extra day is added every 128 years, and we cut it off every 100 years? Yes, we cut off more than we should, and this needs to be returned at some point.

If the first paragraph is clear and still interesting, then read on, but it will be more difficult.

So, in 100 years, 100/128 = 25/32 days of excess time accumulates (that’s 18 hours 45 minutes). We do not make a leap year, that is, we subtract one day: we get 25/32-32/32 = -7/32 days (that’s 5 hours 15 minutes), that is, we subtract the excess. After four cycles of 100 years (after 400 years), we will subtract an extra 4 * (-7/32) = -28/32 days (this is minus 21 hours). For the 400th year we make a leap year, that is, we add a day (24 hours): -28/32+32/32=4/32=1/8 (that’s 3 hours).
We make every 4th year a leap year, but at the same time every 100th year is not a leap year, and at the same time every 400th year is a leap year, but still every 400 years an extra 3 hours are added. After 8 cycles of 400 years, that is, after 3200 years, an extra 24 hours will accumulate, that is, one day. Then another one is added required condition: Every 3200th year must not be a leap year. 3200 years can be rounded up to 4000, but then you will again have to play with added or trimmed days.
3200 years have not passed, so this condition, if it is made this way, is not yet talked about. But 400 years have already passed since the approval of the Gregorian calendar.
Years that are multiples of 400 are always leap years (for now), other years that are multiples of 100 are not leap years, and other years that are multiples of 4 are leap years.

The calculation I gave shows that in the current state, an error in one day will accumulate over 3200 years, but here’s what Wikipedia writes about it:
“An error of one day compared to the year of the equinoxes in Gregorian calendar will accumulate in approximately 10,000 years (in Julian - approximately 128 years). A frequently encountered estimate, leading to a value of the order of 3000 years, is obtained if one does not take into account that the number of days in the tropical year changes over time and, in addition, the relationship between the lengths of the seasons changes.” From the same Wikipedia, the formula for the length of a year in days with fractions paints a good picture:

365,2425=365+0,25-0,01+0,0025=265+1/4-1/100+1/400

The year 1900 was not a leap year, but 2000 was, and special, because such a leap year happens once every 400 years.

For centuries, humanity has created a history that has been passed down from generation to generation. Myths or reality about the leap year that have survived to this day make everyone think about this inexplicable fact.

What is a leap year?

The term "leap year" Latin has a digital value - 2nd/6th. It represents, with scientific point vision - the fourth year exceeding the standard number of days (366).

Leap year historical period

During the reign of Yu. Caesar, the Roman calendar had an additional repeated day, with one date (the twenty-fourth of February).

The Romans counted days and years by looking at the Julian Calendar.

IN Julian calendar, every fourth year was considered a leap year, and the last two days of February were on the same date.

After the death of the Roman ruler, the priests deliberately began to call the third year a leap year. There was a shift in the annual time and people, for this reason, lived as many as twelve leap years.

Thanks to the decree of the new emperor in Rome - Augustus Octavian, everything fell into place. It took sixteen whole years to establish the correct “leap time”.

Sixteen centuries later Orthodox Church reintroduced new changes to the calendar.

Chapter catholic church Pope Gregory XIII made a proposal to calculate the calendar according to new rules. He proposed introducing an additional day in February with a different date (the twenty-ninth of February). On general meeting, before the upcoming Easter, the idea of ​​the head of the Catholic Church was successfully accepted. The Roman calendar had a new chronology. In honor of the ruler of the Catholic Church, it began to be called “Gregorian”.

Modern concept of leap year

It is a well-known fact that a year consists of 365 days. The subsequent fourth year is considered a leap year. It is longer by one day.

In a leap year, February has not twenty-eight days, but twenty-nine, but this phenomenon happens once every four years.

Leap year signs and superstitions

Our Slavic ancestors thought that leap year was a mystical, superstitious year. Probably the reason lies in the distant story of Saint Kasyan.

Saint Kasyan served in the Galilean monastery and was its founder. He became famous through his writing, writing twenty-four essays on the “Interview”, based on a moral, Christian attitude towards faith.

The main flaw in the life of Saint Kasyan was that the date of his birth fell on the last day of February, and even at the end of the year.

According to Slavic belief, the last day of the year was considered the end of a harsh winter. For this reason, the holy monk gained notoriety.

Superstitious Slavs considered the last day of a leap year to be the most difficult. They believed in evil spirits and evil spirits. This is where people's fear of leap years came from.

The signs of a leap year were associated with Saint Kasyan:

  • If Kasyan approached the people, the disease attacked them.
  • Kasyan was close to the animals - their death was inevitable.
  • Wherever Kasyan’s gaze falls, there will be trouble and devastation.
  • Kasyanov's year is approaching unsuccessfully - barren.

According to legend, you don’t need to do a lot of things during a leap year, for example:

  • Play weddings
  • Plan pregnancy, give birth to children
  • Create new projects
  • Go to the forest to pick mushrooms
  • Cut hair
  • File for divorce
  • Borrow money
  • Plant new seeds
  • Do renovations indoors
  • Purchasing real estate

Leap year approaching modern society causes mixed opinions. One part of society believes in his negative actions, the other does not.

The downside of a leap year:

  1. Natural disasters
  2. Disasters
  3. Military conflicts
  4. Frequent accidents
  5. Lost
  6. Fires

The positive side of a leap year

People born in a leap year are creative and talented. Endowed with bright charisma, strong character, love of life (Julius Caesar, Leonardo da Vinci, Elizabeth Taylor, Paul Gauguin).

Today, leap year is perceived as a year of disasters, wars, and disasters. After all, the most terrible events occurred during this period.

People are susceptible to believing something, and most often it is bad. Leap year is perceived as a time of loss, disappointment, and sadness. Is it so? You only have to ask yourself.



The new year 2020 will be a leap year, which means that we will live 1 day more in it - in February, instead of the usual 28 days, there will be 29. The additional 366 day in a leap year on February 29 is due to the fact that the Earth completes its revolution around the Sun in 365 days 5 hours 48 minutes and 46 seconds. To compensate for this difference of almost 6 hours, one day is added to the calendar every 4 years.

Everyone has a different attitude towards the leap year - some consider this period to be the most ordinary year, which does not carry any danger, others are afraid of it and associate many superstitions with this period. In this article we will try to understand all the signs, beliefs and misconceptions associated with the leap year.

Upcoming Leap Years: 2020, 2024, 2028, 2032, 2036, 2040, 2044.

An additional day in a leap year, February 29, is called Kasyanov's day. In Nada, this day is considered one of the most difficult and dangerous. There was a bad attitude towards leap year in folk beliefs associated with a certain Kasyan, about whom there were many legends and beliefs. According to one legend, Kasyan was an Angel who knew all the affairs and plans of God. However, it later turned out that he was a traitor who told all the plans to the demons. For this he was punished - he was beaten on the forehead for 3 years, and for 4 years he was released to Earth, where he already committed evil deeds. According to another legend, Kasyan was a saint, but he broke the law and drank alcohol for 3 years, and stopped for 4 years.
