Each month, on the Shabbat before Rosh Chodesh, we bless the upcoming new month with a special blessing recited in the synagogue. The one exception is this Shabbat: although it proceeds Rosh Hashanah -- which is also the first day of the month of Tishrei -- we do not recite the special "blessing for the month," just as all other Rosh Chodesh elements are absent from the Rosh Hashanah prayers and observances. According to the Baal Shem, "G-d Himself blesses the month of Tishrei, and it is with the power of this blessing that the people of Israel bless the other months of the year."
