Minhagei Rosh Chodesh
It is customary for women to refrain from performing certain types of work on Rosh Chodesh (see note).
It is customary to refrain from cutting nails on Rosh Chodesh.
The Frierdiker Rebbe cites an “ancient custom” to study a possuk from the kapitel corresponding to one’s age each Rosh Chodesh, along with Rashi’s explanation (and additional commentaries).
For Tehillim with Rashi, visit www.chabad.org/16222.
If there are less than twelve pesukim in your kapitel (or less than thirteen in a leap year), when you finish the kapitel, learn it a second time. If there are more than twelve (or thirteen) pesukim in your kapitel, study enough pesukim each Rosh Chodesh to finish the kapitel over the course of the year.
The Rebbe encouraged arranging farbrengens (in shul) on Rosh Chodesh.
