Business opening dates in 2025, from the Chinese almanac

The days in 2025 the almanac lists Opening a business (开市) as good for, and not also as to avoid: 79 of them, 18 at a weekend.

Custom adds one more rule: skip a day that clashes with the year animal of anyone it is for — two branches six apart, directly opposite, clash (Liu Chong, 六冲). Stricter practice also skips a day that clashes with the animal of the day each person was born on. Enter the birth dates and those days drop out.
