Does the Gregorian calendar refer to the lunar calendar? Do you use the Gregorian birthday to check the constellations?

Gregorian calendar, of course. Constellation is a kind of divination method circulating abroad, which is based on the constellations in the sky, but there is no lunar calendar abroad. This is the same as looking up the zodiac according to the lunar calendar.

There are still many people who can't tell what is the solar calendar and what is the lunar calendar. Let me explain in detail here: Lunar calendar refers to a saying of China, which is a small character at the bottom of the calendar, with the word "Chu" before the date 1 to the date 10, and 24 solar terms, villagers' birthdays and zodiac signs are calculated according to this algorithm; Gregorian calendar and Gregorian calendar refer to the days that we usually say "no", that is, the days that are big on the calendar and expressed by numbers. Most of our lives are calculated according to this, and so are the constellations.
