Mar Cheshvan is understood by rabbinic tradition to be a “bitter” month because it is bereft of holidays. This is in stark contrast to Tishrei, which has a plethora (a term I learned from the Three Amigos – who says nothing good comes out of Hollywood?), like Rosh Hashana, Yom Kippur, and Sukkot.
That being said, it can be just a bit overwhelming with so many sacred and wonderful experiences all crammed in together. Whoever came up with the idea of taking a month off from sacred celebrations (excluding Shabbat of course), was actually a fairly brilliant person (or God). They rank up there in my book with those who invented frying just about any type of food, as well as those who came up with the idea of mixing chocolate with peanut butter, or chocolate with almonds, or chocolate with wafers, or chocolate with more chocolate. You get the idea.
So for me personally, there are no Cheshvan blues. Besides who has the time to think about it anyway? And as an added bonus, its sweeps, so a month of Heroes and Simpsons uninterrupted.
