Each month (except before Rosh Hashana), we say the blessing over the new month (birkat ha'chodesh). On Shabbat morning preceding the new moon, at the end of Torah reading, we announce the coming of the new month (Rosh Chodesh), including:

• The name of the month.
• The day and time the new moon will appear in Jerusalem.
• The day of the week that begins the new month (and sometimes the last day of the previous month).

We say some prayers that ask for good health, prosperity, and other good things.
