When moving from one house to another, there are different customs and laws to consider. Most of these were mentioned by the Rebbe on various occasions.
- It's best to move on a Tuesday. If that's not possible, any day is fine (except Mondays, Wednesdays, and obviously Saturdays and holidays).
- One must affix the Mezuzot to all the doors of the new house as soon as one moves in.
- First, you must bring bread, salt, a Chumash (five books of Moshe), a book of Tehillim (Psalms), and a Tanya (book of Chabad Hasidic philosophy).
- There should be a donation box in the new house to make this new home a home of Tzedakah. It is also customary to attach a donation box to the kitchen wall.
Dear Rabbi Tuvia,
Why are Mondays and Wednesdays included among the days that are not good for moving house?
With gratitude,
B"H
Hello Ariel, in a letter dated 8 Elul, 1957, the Rebbe wrote that it's best to move on a Tuesday, which is the third day of the week, and in the Torah's creation narrative, the words "which is good" appear twice. Therefore, it's an auspicious day.
On the other hand, the Rebbe writes that any other day is fine, except Monday and Wednesday.
This is what the Rebbe wrote. The explanation is that on those two days, divine judgment shines; they are "hard" days, so to speak.
On Monday, in the creation narrative, the division appears, between the waters above and those below. The division is "gevurah," judgment.
On Wednesday the luminaries of the sky are created, which are also related to judgment (in the original biblical text, luminaries is spelled meorot, without the letter vav, which indicates meerat, curse).
Greetings!!
