Yom Kippur katan

Tonight is Rosh Chodesh Elul, One month until rosh hashanah. Have you ever heard of yom Kippur katan, the day before rosh chodesh each month? YOM KIPPUR KATAN (Heb. יוֹם כִּפּוּר קָטָן; lit. "minor day of atonement"), the eve of the new month which became for the pious a day of fast and repentance. The custom of keeping Yom Kippur Katan is a late one, and is not mentioned in the Shulḥan Arukh. It began among the kabbalists of *Safed in the second half of the 16th century and is first spoken of by Moses *Cordovero. The waning of the moon was conceived by the kabbalists as a symbol of the exile of the Shekhinah ("Divine Presence") and the diminution of the power of holiness during the Exile, and its renewal as a symbol of the return to perfection in the age of Redemption. They based this conception on the talmudic legend according to which God had said to Israel: "Bring atonement upon me for making the moon smaller" (Ḥul. 60b).   Yom Kippur Katan

The day before each Rosh Chodesh (beginning of the month) is referred to as 'Yom Kippur Katan," the "Little Yom Kippur." R' Gedalya Schorr, in explaining why this is the case, first discusses the purpose of Yom Kippur. Yom Kippur, simply stated, is a day for one to take an accounting of what he or she has accomplished or failed to do. It is time for people to inspire themselves, to arouse within their heart and soul a desire to accomplish more, to strive for greatness. The very end of a month, when the moon is barely visible, is an appropriate time to remind ourselves of what we are to be doing with our lives. We can gaze upwards and see almost none of the moon, knowing that a mere two weeks later, the moon will be full. Similarly, we can gaze within ourselves and see not even a tiny spark of inspiration or desire to strive for greatness. At the same time, we should know that we have the ability within us to shine brightly. Right before we begin a new month, we should inspire ourselves to improve, regardless of the method we employ to do. For this reason, specifically the day before Rosh Chodesh is set aside for a day of self improvement and introspection, thus earning it the name Yom Kippur Katan
