How to calculate the number of departures?

For those born in male and female years, count down from the day of birth to the next festival, depending on how many days are left. For those born in the year of male yin and female yang, count backwards from the day of birth to the last festival to see how many days there are. Three days equals one year, that is, one day equals four months and one hour equals five days.

The traditional delivery time calculation is based on each solar term 15 days, that is, 360 days per year, which is inconsistent with the actual solar year of 365, which is 5: 48: 45 and 56 16. The accurate calculation method is as follows: solar year 365+094/360 =1.4838+063856666.
