Editing Rosh Chodesh (section)

===Announcement===
Despite the existence of a fixed calendar, Rosh Chodesh is still announced in [[synagogue]]s on the preceding [[Shabbat]] (called [[Shabbat Mevarchim]] — The Shabbat of Blessing [the new month]). The announcement is made after the reading of the [[sefer Torah]], before returning it to the [[Torah ark]]. The name of the new month, and the day of the week on which it falls, is given during the prayer. Some communities customarily precede the prayer by an announcement of the exact date and time of the new moon, referred to as the ''molad'', or "birth".<ref name="''Tehillat HaShem'', p.
