How to calculate the delivery time

Now the accurate calculation method is as follows: the calculation of the first year of the Universiade begins with people's birthdays, boys born in the year of Yang and girls born in the year of Yin are calculated in turn, and boys born in the year of Yin and girls born in the year of Yang are calculated in reverse.

Sequential calculation: refers to the time calculated according to the date and time of birth until the future festival. Look at it for a few days, then count three days as one year, one day as four months and one hour as five days. In this way, the accurate delivery time of this person can be calculated.

Back calculation: The difference between back calculation and forward calculation is that the date of birth is back calculated to the date of the last holiday, and other methods are exactly the same as forward calculation. For example, giving birth to a boy at the end of the fifth day of November in the Sino-Japanese War is a male life in the Yang year.

From the date of his birthday to the date of the coming festival, when Cha Jia's five-year snow festival falls on 1 1 month 14, and from the end of the fifth day to the fourteenth day, he will get eight days and five hours, three days is 290 days more than two years old, and three years is 70 days less than three years old.
