1974 is a leap year. What is a leap year

Every 4 years we are faced with the fact that in February, instead of the standard 28 days, there are 29. A leap year is coming. This is due to the fact that the Earth revolves around the sun a little faster than 365 days. To compensate for this phenomenon, a leap year was invented and put into practice, which lasts 366 days by adding an extra day in February.

When is a leap year, how to determine

The methods of determination are quite simple and accessible to any person. They do not require any serious mathematical background:

2. A leap year is always divisible by 4 without a remainder. Let's say 2012 is a leap year because 2012:4=503.0, so the remainder of the division is 0.

3. You can view the calendar for the year under study and compare it with the next one by day of the week. If the gap is 1 day, then the analyzed time interval is not a leap year - its length is 52 weeks and 1 day, if the gap is 2 days, then, accordingly, the year is a leap year.

Are there exceptions?

Yes, there are. In order to more fully harmonize the astronomical and calendar years, it was decided not to make leap years those years that end in 00, that is, the beginning of each century. But here there is an exception: every 4th of these years (ending in 00 - 400, 800, 1200, 1600, 2000, 2400, ...) are also leap years.

History of appearance

The very concept of a leap year appeared at a time when scientists proved that the astronomical year has 365 days and approximately 5 hours and 49 minutes. This happened under Julius Caesar, who was known as a fairly progressive ruler. Since then, 1 extra day has been added to the calendar.

The ancient Romans counted the days until the beginning of the next month, and we determine the elapsed from the beginning of the current month. Suppose February 22 for us is the 22nd day of the month, and for the Romans it was the 6th day before the start of the new month. In a leap year, February has two 6th days. "Second sixth" from Latin and gave the name "leap".

The next stage was the Julian calendar, where every third year became a leap year. By the way, in our days it is on it that holidays are determined. We use the Gregorian calendar, and we have a leap year every fourth year.

Superstitions and fears

It is generally accepted among the people that leap years are very unfortunate, and sometimes tragic. Even the Romans began to consider this year bad, because of the "sixth day" the fast increased by one day (it lasted until the beginning of March). The odious holiday "Kasyanov's Day", which was already celebrated by our ancestors, added to the mysticism. It was set for February 29th.

It is believed that on a leap day it is highly undesirable to radically change the usual way of life: get married, move, change jobs, have children, especially the first child.

Is 2019 a leap year or not? 2019 will not be a leap year. From year to year, the approach of the new year causes unrest among superstitious people. What will the upcoming 2019 year of the Pig be like, Leap year or non-leap year.

Interest is based on folk signs and superstitions associated with the addition of an additional February 29th. One day, February 29, is added to the calendar every four years. The previous Leap Year was 2016. When is the next Leap Year? The next one will be in 2020, four years from now.

Razgadamus considers it educational. How many days are in a leap year? A leap year (or popularly called Vysokosny) is considered every fourth year. Its duration is 366 days, one more than the duration of a common year, thanks to extra day– 29 February. In normal, non-leap years, February has 28 days.

2019 Leap year or not, worries superstitious people and is primarily of interest to those people whose birthday falls on February 29th. It turns out that those born in a Leap Year on February 29 have to celebrate their birthday every four years or postpone the celebration to March 1.

The leap year differs from the usual one in duration, it is longer by 1 day. But since ancient times, people have been afraid of the onset of such a four-year period, instilling fear of impending misfortune.

Exist folk omens, according to which the arrival of a Leap Year means the onset of an unlucky period of time in the life of every person for four years.

Signs in Leap Year: Do's and Don'ts

Believe in omens or not? February 29 is popularly called Kasyan's Day (or Kasyanov's Day), and it is considered unlucky for the birth of a child.

If you believe it, then 2017 is the year of the widow, the year of the widower is 2018, both dates are not suitable for a wedding. BUT couples who have scheduled a wedding in 2019, prosperity and well-being await.

A leap year gives rise to many superstitions and rumors, which boil down mainly to the fact that this year is unlucky and rich in negative events. Let's see if this is the case.

Leap year: a bit of history

The word "leap" is of Latin origin, translated as "second sixth". According to the Julian calendar, the year lasted 365.25 days, while every year the day shifted by 6 hours. Such an error could confuse the ancient men, so that this did not happen, it was decided that every fourth year would consist of 366 days, and February would become a day longer. This year is called a leap year.

In Russia, there were many legends about the appearance of leap years, each of which was considered unlucky.

Legends about the appearance of a leap year in Russia

February 29 is also called in honor of St. Kasyan Kasyanov Day. Being a bright angel, he was tempted by tricks evil spirits and went over to the side of the devil. However, later he repented and prayed to the Lord for mercy. Having mercy on the traitor, God assigned an angel to him. He put Kasyan in chains and, at the behest from above, beat him on the forehead with an iron hammer for 3 years, and let him go on the fourth.

According to another legend, Kasyanov's day is the day of his name day. However, the saint each time got dead drunk for three years and came to his senses only in the fourth year. Therefore, he is supposed to celebrate his day so rarely.

There is a third legend: walking along the road, Saint Kasyan and Nicholas the Wonderworker met a peasant. He asked for help, as his wagon got stuck in the mud. To which Kasyan replied that he was afraid to stain the robe, and Nikolai helped. The saints came to paradise, God noticed that Nicholas's robe was dirty and asked what was the matter. The Miracle Worker told him what had happened. Then God noticed that Kasyan's robe was clean, and asked if they weren't walking together? Kasyan replied that he was afraid to get his clothes dirty. God understood that the saint was cunning and made it so that his name day comes every 4 years. And the birthday of Nikolai for his kindness - twice a year.

Leap years were notorious in Russia: we will not continue the list of legends for a long time, here is one example: honest people tried to complete all their affairs before February 29th. Many did not dare to leave the house, the sun on this day was called the "Eye of Kasyan", they were afraid to fall under the sun, so that Kasyan would not jinx them and send illness and suffering.

Leap year superstitions

As in ancient times, modern world often there are signs and superstitions, not with better side characterizing leap years (the list is given below):

• We need to postpone marriage in a leap year. Such a marriage will not be lasting, the young will quarrel, and the newly created family will incur troubles and misfortunes.
• You need to wait with the sale, purchase, exchange of real estate or building a house. The deals made this year will not be profitable and will inevitably lead to the ruin of the parties. The new home won't last long.
• Any undertakings are dangerous - job change, moving, starting a business. The sign is understandable: the presence of the 29th day in one of the winter months can characterize the whole year as not being what it should be. Therefore, unsure of own forces it is easier for a person to give up something new than to make efforts to start and develop a business.
• You can not get pregnant and give birth, as the birth will be difficult, the baby may be born unhealthy. Or his life will be hard and joyless.

• It is believed that leap years entail natural disasters and disasters: fires, floods, drought.

• The year 2000 was also a leap year.

Leap years: 21st century list

To this day, many fearfully wait for a leap year, psychologically setting themselves up for trouble and explaining misfortune by the presence of an extra day in February.

Leap years, list since 2000: -04; -08; -12; -16, and then - every fourth year.

Instead of a conclusion

According to statistics, only a small number of all the troubles and disasters occur in leap years. The superstitions that exist to this day can be explained by the fact that people who closely follow the troubles and misfortunes that happened in leap years, attached exaggerated significance to what was happening solely because of the unflattering glory of the latter.

People who believe too much in leap year superstitions would like to wish to pay more attention to positive changes and events. And then, perhaps, a list of good signs rehabilitating leap years will appear.

Leap year (lat. bis sextus - “second sixth”) - a year in the Julian and Gregorian calendars, the duration of which is 366 days - one day more than the duration of a regular, non-leap year. In the Julian calendar, a leap year is every fourth year; in the Gregorian calendar, there are exceptions to this rule.

A year is a conventional unit of time, which historically meant a single cycle of seasons (spring, summer, autumn, winter). In most countries, the calendar length of the year is 365 or 366 days. At present, the year is also used as a temporal characteristic of the revolution of planets around stars in planetary systems, in particular the Earth around the Sun.

The calendar year in the Gregorian and Julian calendars is 365 days in non-leap years and 366 days in leap years. The average length of the year is 365.2425 days for the Gregorian and 365.25 days for the Julian calendar.

The calendar year in the Islamic calendar contains 353, 354 or 355 days - 12 lunar months. The average length of the year is 354.37 days, which is less than the tropical year, and therefore Muslim holidays "roam" according to the seasons.

The calendar year in the Jewish calendar contains 353, 354 or 355 days in simple year and 383, 384 or 385 days in a leap year. The average length of the year is 365.2468 days, which is close to the tropical year.

The length of the tropical year (the time between the two vernal equinoxes) is 365 days 5 hours 48 minutes 46 seconds. The difference in the duration of the tropical year and the average Julian calendar year (365.25 days) is 11 minutes 14 seconds. Of these 11 minutes and 14 seconds, approximately 128 years add up to one day.

As the centuries passed, a shift in the day of the vernal equinox was noticed, with which church holidays. To XVI century the spring equinox came about 10 days earlier than March 21, used to determine the day of Easter.

To compensate for the accumulated error and avoid such a shift in the future, in 1582, Pope Gregory XIII reformed the calendar. To mean calendar year better matched the solar, it was decided to change the rule for leap years. As before, a year remained a leap year, the number of which is a multiple of four, but an exception was made for those that were a multiple of 100. From now on, such years were leap years only when they were also divided by 400.

In other words, a year is a leap year in two cases: either it is a multiple of 4, but not a multiple of 100, or it is a multiple of 400. A year is not a leap year if it is not a multiple of 4, or it is a multiple of 100, but not a multiple of 400.

The last years of centuries ending in two zeros are not leap years in three cases out of four. So, the years 1700, 1800 and 1900 are not leap years, since they are a multiple of 100 and not a multiple of 400. The years 1600 and 2000 are leap years, since they are a multiple of 400. The years 2100, 2200 and 2300 are non-leap years. In leap years, an extra day is introduced - February 29. The Catholic world lives according to the Julian calendar. Unlike the Julian calendar, the Gregorian calendar takes into account only one object - the Sun.

We currently live by the Julian calendar new style), before the revolution they lived according to the Gregorian ( old style). The difference between the old and new styles was 11 days in the 18th century, 12 days in the 19th century, and 12 days in the 20th XXI centuries- 13 days. In the 22nd century, this difference will already be 14 days. The Gregorian calendar was introduced under Soviet rule on February 14, 1918 (after January 31, it was no longer February 1, but immediately the 14th). The last leap year was , the next one will be .

1996, 1992, 1988, 1984, 1980, 1976, 1972, 1968, 1964, 1960, 1956, 1952, 1948, 1944, 1940, 1936, 1932, 1928, 1924, 1920, 1916, 1912, 1908, 1904, according to Gregorian 1900 is a non-leap year, Julian is a leap year. 1896.

Note: For most computer and mobile systems Valid dates are from December 13, 1901, 20:45:54 GMT to January 19, 2038, 03:14:07 GMT. (These dates correspond to the minimum and maximum value of a 32-bit signed integer). For Windows, valid dates are from 01-01-1970 to 01-19-2038.

and why is 1900 not a leap year? A leap year occurs every 4 years, i.e. Divisible by 4, it's a leap year. And no more divisions by 100 or 400.

Asking questions is normal, but before you say something, study the materiel. The earth revolves around the sun in 365 days 5 hours 48 minutes 46 seconds. As you can see, the rest is not exactly 6 hours, but 11 minutes 14 seconds less. This means that by making a leap year we add extra time. Somewhere in 128 years, extra days accumulate. Therefore, every 128 years in one of the 4-year cycles, a leap year is not necessary to get rid of these extra days. But to simplify, a leap year is not made every 100th year. Is the idea clear? Good. But how then to proceed, because an extra day is added every 128 years, and we cut it every 100 years? Yes, we cut off more than it should be, and this must be returned sometime.

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 accumulate (this is 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 (this is 5 hours and 15 minutes), that is, we subtract the excess. After four cycles of 100 years each (after 400 years) we will subtract an extra 4*(-7/32)=-28/32 days (this is minus 21 hours). On the 400th year, we make a leap year, that is, we add a day (24 hours): -28/32+32/32=4/32=1/8 (this is 3 hours).
We make every 4 years a leap year, but at the same time every 100 years is not a leap year and at the same time every 400 years 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 again you have to play with added or truncated days.
3200 years have not passed, so this condition, if it is made so, is not yet spoken of. But 400 years have already passed since the approval of the Gregorian calendar.
Years divisible by 400 are always leap years (for now), other years divisible by 100 are not leap years, other years divisible by 4 are leap years.

My calculation shows that in the current state, an error of one day accumulates over 3200 years, but this is what Wikipedia writes about this:
“An error of one day compared to the year of the equinoxes in the Gregorian calendar will accumulate in about 10,000 years (in the Julian - in about 128 years). A frequently encountered estimate, leading to a value of the order of 3000 years, is obtained if we do not take into account that the number of days in a tropical year changes with time and, in addition, the ratio between the lengths of the seasons changes. From the same Wikipedia, the formula for the length of the 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.
