I was born on April 20th of the lunar calendar. What constellation is it?

It depends on your date of birth, which corresponds to the 20th day of April in the lunar calendar. Constellations are judged according to the Gregorian calendar. Because the corresponding dates of the lunar calendar and the solar calendar vary greatly every year, you may be Taurus Gemini Cancer just by looking at the lunar calendar. If you are in 2003, and April 20th of the lunar calendar corresponds to May 20th of the solar calendar, it is Taurus.
