This question already has an answer here:

I have heard that the reason we do not Bench Rosh Chodesh Tishrei is in order to confuse the Satan. Now the Satan is no fool. How is the Satan getting confused when we pull this trick year after year?

  • @yydl: see page 4 of colelchabad.org/assets/pdfs/Elul_English.pdf : The Alter Rebbe said in the name of the Baal Shem Tov: “Tishrei is blessed by the Holy One, blessed be He, Himself. And with the power of this blessing, the Jews bless the other eleven months of the year – Menachem Sep 1 '13 at 5:28
