Going back to its Biblical origins of the new moon, from here:

Rosh Chodesh (or Hodesh; Hebrew: ראש חודש, "Head/Beginning [of the] Month") is the name for the first day of every month in the Hebrew calendar, marked by the appearance of the new moon. It is considered a minor holiday, akin to the intermediate days of Passover and Sukkot...

In the Book of Numbers, God speaks of the celebration of the new moon to Moses, "And on your joyous occasions - your fixed festivals and new moon days - you shall sound the trumpets over your burnt offerings and your sacrifices of well-being."...

According to the Talmud (tractate Megillah 22b), women are exempt from work on Rosh Chodesh, and Rashi, in commenting on this passage, delineates the activities from which they may refrain: spinning, weaving, and sewing — the skills that women contributed to the building of the Mishkan (Tabernacle). The midrash Pirke De-Rabbi Eliezer explores this exemption in chapter 45:

Aaron argued with himself, saying: If I say to Israel, Give ye to me gold and silver, they will bring it immediately; but behold I will say to them, Give ye to me the earrings of your wives and of your sons, and forthwith the matter will fail, as it is said, "And Aaron said to them, Break off the golden rings." The women heard (this), but they were unwilling to give their earrings to their husbands; but they said to them: Ye desire to make a graven image of a molten image without any power in it to deliver. The Holy One, blessed be He, gave the women their reward in this world and the world to come. What reward did He give them in this world? That they should observe the New Moons more stringently than the men, and what reward will He give them in the world to come? They are destined to be renewed like the New Moons, as it is said, "Who satisfieth thy years with good things; so that thy youth is renewed like the eagle."

Such lovely images there. And as the new moon was the traditional beginning of the month in times of old, this feels the perfect time to share about one's love letters from God...
