The baby was born at 7 o'clock in the morning. Books and computers say it's Chen Shi, and fortune tellers say it's Shi Mao. How to calculate it?

Determining the birth time of a child needs careful verification to ensure accuracy. In general, the date of birth should be based on the birth certificate recorded by the hospital or other medical institutions. If there are differences, it is best to consult professional medical institutions or local government agencies to get the correct birth time.

After determining the time of birth, you can use the eight-character arrangement to calculate the child's chart. The eight-character arrangement can only analyze a general trend of the chart, but can't be accurate to the specific details. So even if there is a little error in the birth time, it will not have much impact on the analysis of the whole chart.

In the eight-character arrangement, Chen Shi and Shimao are both time units in the ancient timing system. Chen Shi means 7 am to 9 am, and Shi Mao means 5 am to 7 am. Therefore, if the child was really born at seven o'clock in the morning, then the calculation method according to the eight-character arrangement should belong to Shi Mao. But different eight-character typesetting algorithms may be different, so there may be different results.

To sum up, the date of birth of the child should be based on the birth certificate recorded by the hospital or other medical institutions. If there are differences, it is best to consult professional medical institutions or local government agencies to get the correct birth time.
