10 June 29th is not an auspicious day, nor a good day. 10 June 29th is the anniversary of a month's death. Don't use it for large-scale activities, it is not a good day to hold large-scale activities. I suggest you change a lucky day.
The ancients paid attention to time, place and people, and all three were prepared for great things. From ancient times to the present, whenever there are major activities such as offering sacrifices, getting married, opening business, building houses, etc. People should ask numerology and geomantic omen to choose a "auspicious day" and pray for good luck to avoid evil spirits and complete it smoothly. "auspicious day" is often used in our daily life. There are two main calculation methods, one is twelve values, and the other is twelve people supporting twelve gods.
