What year is the Gregorian calendar in 2004?

In the Gregorian calendar (Gregorian calendar), a year with leap days is called leap year, which is generally 365 days and 366 days. Because the earth's cycle around the sun is 365 days, 5 hours, 48 minutes and 46 seconds (365,438+09 days), which is the tropic year, the Gregorian calendar sets a year as 365 days. The remaining time is about one day in four years, plus February, so the normal year is 365 days, February is 28 days, leap year is 366 days, and February is 29 days. Therefore, there are 97 leap years every 400 years, with an additional day at the end of February, and leap years have 366 days. Calculation method of leap year: the number of years in the calendar year can be divisible by four, which is a leap year; Divided by 100 but not divided by 400 is a normal year; Leap years can be divisible by 100 or 400. For example, 2000 is a leap year, but 1900 is not.

In the China lunar calendar, a year with a leap month is called a leap year. The general year is 12 months, 354 or 355 days, and the leap year is 13 months, 383 or 384 days. As a kind of lunar calendar, the number of days per month depends on the monthly loss, and the time of one year is based on 12 months. In order to close the earth's cycle around the sun, that is, the tropic year, one month is added every two to four years, and the added month is a leap month, so the leap year of the lunar calendar is 13 months.

There is no thirteenth month in the lunar calendar. According to the calendar rules, leap months are repeated in the same month from February to 10, and the repeated months are leap months. For example, the leap month after April is called leap April.

Lunar leap year leap month calculation, three-year leap, five-year leap, 19 leap; The lunar calendar basically takes 19 as a cycle, corresponding to the same time in the Gregorian calendar. For example, in the Gregorian calendar, May 27th, 200 1, May 27th 1982 and May 27th 1963 are the fifth day of leap April.

The month of the leap month is inferred according to the laws of the lunar calendar, mainly according to the coincidence degree with the 24 solar terms of the lunar calendar; The number of leap months in the lunar calendar is the same as that in normal months, both of which are 29 or 30 days.

The so-called "leap" in the lunar calendar is only called leap year and leap month, and there are also leap years in the Gregorian calendar.

2004 is a leap year in the Gregorian calendar, with 29 days in February, one more day than the 28 days in February in normal years. The ancient Egyptians and calendar experts in China during the Spring and Autumn Period calculated that a year was 365 days. In fact, the time for the earth to revolve around the sun (that is, a year in the solar calendar) is 365 days, 5: 48: 46. In this way, four years will be extended by 23: 15 minutes and 4 seconds, close to one day (24 hours). Therefore, calendar experts stipulate that a "leap year" is set every four years, that is, one day is added in February of this year, also known as "leap day", and later it is stipulated that 97 leap years are set every 400 years.

2004 is the year of Shen Jia in the lunar calendar and also a leap year. Lunar calendar calls it "leap month", that is, one more month in a year, that is, 13 months. In the ancient calendar of China, there was a lunar calendar, in which the period of the full moon was one month, the odd-numbered month in the big month was 30 days, the odd-numbered month in the small month was 29 days, and the year was 354 days, which was 1 1 day less than the time for the earth to revolve around the sun, and more than 33 days less than three years. Therefore, calendar experts stipulate that a "leap month" should be set every three years. For the sake of accuracy, it is also stipulated that seven leap month years should be set at 19.

Each month contains two solar terms. The working people in ancient times called the first solar terms (beginning of spring, Jing Zhe, Qingming, Long Summer, Busy Middle School, Slight Summer, beginning of autumn, Bailu, Cold Dew, beginning of winter, Heavy Snow and Slight Cold) "solar terms". The last solar term (rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, summer heat, autumn equinox, first frost, light snow, winter solstice and severe cold) is called "Zhong Qi". After the Han dynasty, the month without neutral atmosphere was designated as the leap month of the first lunar month, and this rule of placing leap has continued to this day.

There is no thirteenth month in the lunar calendar. According to the calendar rules, the emissions of leap months are repeated from February to the same month after 10. The repeated month is a leap month, calculated by the leap month of the lunar leap year, with a leap of 3 years, a leap of 5 years, and a leap of 19. The lunar calendar basically takes 19 as a cycle, corresponding to the same time in the Gregorian calendar. If you were born on May 27th of Gregorian calendar 1982, then your birthday on May 27th of Gregorian calendar 200 1 year is also on the fifth day of leap April, which means that your Gregorian birthday will coincide with Gregorian birthday every 19 years.
