Gregorian calendar auspicious day query 2016 is March 23 suitable for tomb building?

There is something wrong with your question. Is it March in the solar calendar or March in the lunar calendar? March 23rd of the solar calendar is Chen Jiari, and the lunar calendar can't be used except this day. On March 23 of the lunar calendar, although the fourth, fourth and fourth days of the lunar calendar are all ecliptic days, the ancient date book says it is not suitable for setting up a tomb.
