The arrangement of "1" and "eight characters" is not based on a certain year of the Gregorian calendar, nor on the first day of the first lunar month, but on the first day of February, but on the solar term' beginning of spring' of the lunar calendar, and the twelve solar terms are the handover points of each month. Midnight every night is the daily handover point.
2. Arrange the annual branches and fees: First of all, it should be noted that the annual handover time is based on the' beginning of spring' Festival, not on the first day of the first lunar month or Gregorian calendar 1.
3. There are several common situations in arranging annual expenses: if the lunar calendar has reached the first day of the first month and the Spring Festival has not yet been established, it should be arranged according to the previous year. Example: Someone was born on the 10th day of the first month of 1974, because the Spring Festival of 1974 falls on the 13th day of the first month. This person's birth date has not been handed in yet, so his annual trunk should be 1973' Guichou' trunk.
4. Pay in advance. For example, a person was born on 19741February 25th, so "beginning of spring" on February 24th of the lunar calendar/kloc-0 in 2007 has paid for 75 years of festivals, so his annual trunk should be classified as "Yi Mao".
5. For example, this person was born sometime on 1974 1 month 14. Since beginning of spring was at the end of 13th, his annual expenditure should be Jia Yin. For example, someone was born on 19741February 23rd. As the Spring Festival of 1975 has not yet passed, his annual expenditure is Jiayin.
