Does the second lunar month of 2021 have 30 days? How often does the 30th day of the second lunar month come?
The number of days in the lunar calendar is different in different months. So, let’s take a look at whether there are 30 days in the second month of the lunar calendar in 2021? After the Spring Festival, the various festivals in the first month of the lunar calendar will soon follow. Following the 2021 first month special topic of Shuimoxiansheng.com, let’s count how many important traditional festivals and customs there are in this month.Does the second lunar month of 2021 have 30 days?The second month of the lunar calendar in 2021 has thirty days, and the first day of the second month of the lunar calendar in 2021 corresponds to March 13, 2021 in the Gregorian calendar.The corresponding Gregorian calendar time for February 30th of the lunar calendar in 2021 is April 11th, 2021. Therefore, the second lunar month in 2021 has 30 days. How often does the 30th day of the second lunar month come?The first day of every lunar month is the "new moon" (when the moon is between the sun and the earth, with its dark half facing the earth). Sometimes there may be two long moons, or two short moons in succession. Since the synodic month is slightly longer than 29 and a half days, there are approximately 53 long months and 47 short months in every 100 calendar months in the lunar calendar.The lunar calendar basically has 12 months as a year, but the time of 12 synodic months is 354.3667 days, which is about 11 days different from the tropical year. This means that every three years there will be 33 extra days, or more than one month. In order to eliminate the extra days, one month is added every three years. This is the leap month in the lunar calendar. A year with a leap month is also called a leap year. So there are 13 months in a leap year in the lunar calendar. As for which month to add as a leap month, it is determined by the solar terms. The length of the lunar months is very irregular. Sometimes there are two, three, or four long months in a row, or two or three short months in a row. The length of the years is also different, and the gap is very large. The distribution dates of the solar terms and the central terms in the lunar calendar are very unstable, and the range of date fluctuations is very large. From this perspective, the lunar calendar seems to be very complicated. actually. The lunar calendar does follow a certain cycle: since the number of days in nineteen tropical years is almost equal to the number of days in nineteen lunar years, the lunar calendar remains almost the same every nineteen years. Every nineteen years, the first day of each month in the same lunar month is generally the same as the solar calendar day or differs by one or two days. Every nineteen years, the dates of the solar terms and the mid-terms are roughly repeated, with individual differences of one or two days. The leap month is repeated or differs by one month every nineteen years. |
