I estimated that my date was born at four o'clock, and later his mother said it was at half past four. What's the difference between this half hour?

This bosom friend, born at four o'clock, is the same as at half past four. Both of them are from Yin Shi. Yin Shi is from three to four fifty-nine. Yin Shi is called Pindan, that is, morning, dawn and sunset. It is a time of alternation between day and night.

Fortune telling is calculated by the hour. As long as it is within the hour, it doesn't matter with every minute. Please rest assured!
