What day is Gregorian calendar 18?

I originally wanted to choose 165438+ 10/8, but according to the old yellow calendar, 18 is the Year of the Monkey. What does this mean? The baby was born as a tiger this year. Does it matter?

According to the numerology advocated by China in Zhouyi, the auspicious day for your rich baby is to avoid the solar calendar 1 1/2 11115,1/kloc.

-I wish mother and son peace and health!
