1995 what is the sign of the birthday in August of leap year 12?

8 12 is Leo, first, the solar calendar.

There are 365 days, 5 hours, 48 minutes and 46 seconds in a year. However, the number of days in a year must be an integer, so a year is 365 days, and the remaining 5 hours, 48 minutes and 46 seconds accumulate to one day in April, so one day is added every four years, which is called "leap year". A year without leap days is called "average year", with 365 days in average year and 366 days in leap year.

However, after four years of leap, it's only 23: 00, 15 minutes and 4 seconds. Today is more than 44 minutes and 56 seconds, which adds up to 100 years, which is 17: 58 minutes and 24 seconds, which is about three quarters of a day. Therefore, a leap is wasted every hundred years, and it will not be wasted until the 400th year. If it is a leap every four years and every 400 years, it will take more than 2: 53 minutes and 20 seconds, and it will take eight 400 years, that is, 3200 years, to make up for the difference the next day.

Second, the lunar calendar

The lunar calendar may have originated in China and is based on agriculture, so the calendar must be based on service agriculture.

The lunar calendar is based on the new moon. The time of the first month of the lunar calendar is 29. 5366 days, so the lunar calendar is also 30 days for the big month and 29 days for the small month. The size of the lunar calendar is determined by calculation, and sometimes there may be two big months or two consecutive small months. Because the first month of the lunar calendar is slightly longer than 29 and a half days, there are about 53 big months and 47 small months in every 100 calendar month. The lunar calendar basically takes 12 months as a year. But the time of 12 moon is 354. 3667 days, which is about 1 1 day different from the tropic year of the solar calendar, so there will be 33 days more every three years, that is, one month more. In order to eliminate the extra days, one month will be added every three years, which is the leap month of the lunar calendar. A year with a leap month is called a leap year, so the leap year of the lunar calendar has 13 months, and which month to run depends on the solar terms.

Which month of the lunar leap depends on the 24 solar terms in a year. The twenty-four solar terms of the China lunar calendar are divided into twelve solar terms and twelve solar terms. The twelve solar terms are: beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, Heavy Snow and Slight Cold; The twelve kinds of qi are: rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, great summer heat, summer heat, autumn equinox, first frost, light snow, winter solstice and severe cold. The twenty-four solar terms of the lunar calendar are postponed month by month. So in some lunar months, the gas drops at the end of the month, and it will be out of gas next month. This coincides with the year when we need leap month. Therefore, it is stipulated in the lunar calendar that only neutral months are considered leap months, and the following months are called moist months. For example, in 2006, the intense heat of Zhongqi fell on July 30th of the lunar calendar, so there will be no next Zhongqi autumnal equinox in mid-August, so July is a leap year.
