/kloc-0 was born in September 1993, and his ID card is May 1 day. What constellation is that?

The birthday on the ID card is registered at home. If it is a solar calendar, it is Taurus. But the previous generation probably used the lunar calendar to register their birthdays, so it was 1 May, 9931day. If you change to the solar calendar, it will be Pisces. Of course, the possibility of registration errors cannot be ruled out. It is recommended to ask your family about their actual birthdays and calculate them according to the solar calendar.
