All holidays begin at sundown on the evening before the date specified in the tables below. For example, if the dates for Rosh Hashana were listed as Sep 19-20, then the holiday begins at sundown on Sep 18 and ends at sundown on Sep 20. Dates in bold are yom tov, so they have similar obligations and restrictions to Shabbat in the sense that normal "work" is forbidden.
