Starting the year with a clean house is of good omen, but cleaning the house the first day of the year is considered inauspicious in Feng Shui.
The solution: clean the house the last day of the year.
Clean the house physically (and also smudge it if you wish) on December 31st. On January 1st take it easy, rest, and don’t touch that broom or any cleaning supplies!
Cleaning the house on the first day of the year disturbs the chi, and starting the year with disturbed chi is “bad luck.”
Spend the first day of the year in meditation, read a good book, spend time with people you love, but don’t do anything crazy. That is what the 31st is for, the crazy stuff.
On January 1st, rest and relax.
