Jewish astrologyAstrology in Jewish antiquity (מזלות = mazzalot) is the belief that celestial bodies can influence the affairs of individuals and of entire nations upon the earth. This involves the study of the celestial bodies' respective energies based on recurring patterns that change by the hour, by the week, month, year or by several years (time categories). In each of these time categories one of the seven planetary spheres, or what are known as the seven classical planets: the Sun, Venus, Mercury, the Moon, Saturn, Jupiter, or Mars, along with the month's current Zodiac constellation, come into play and influence the sublunary world.
Hebrew calendarThe Hebrew calendar (הַלּוּחַ הָעִבְרִי), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel. It determines the dates for Jewish holidays and the appropriate public reading of Torah portions, yahrzeits (dates to commemorate the death of a relative), and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside the Gregorian calendar.
ShabbatShabbat (UKʃə'bæt, USʃə'bɑːt, or ʃə'bʌt; Šabbāṯ, ʃa'bat, rest' or 'cessation) or the Sabbath (ˈsæbəθ), also called Shabbos (UKˈʃæbəs, USˈʃɑːbəs) by Ashkenazim, is Judaism's day of rest on the seventh day of the week—i.e., Saturday. On this day, religious Jews remember the biblical stories describing the creation of the heaven and earth in six days and the redemption from slavery and The Exodus from Egypt, and look forward to a future Messianic Age.
Yom KippurYom Kippur (ˌjɒm_kɪˈpʊər,_ˌjɔːm_ˈkɪpər,_ˌjoʊm-; יוֹם כִּפּוּר, Yōm Kippūr, ˈjom kiˈpuʁ, Day of Atonement) is the holiest day in Judaism and Samaritanism. It occurs annually on the 10th of Tishrei, corresponding to a secular date in September or early October. Primarily centered on atonement and repentance, the day's main observances consist of full fasting and ascetic behavior accompanied by long prayer services in synagogue, as well as sin confessions. Yom Kippur is the only day when fasting is permitted on Shabbat.
Gregorian calendarThe Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull Inter gravissimas issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun.
MussafMussaf (also spelled Musaf or Musof) is an additional service that is recited on Shabbat, Yom Tov, Chol Hamoed, and Rosh Chodesh. The service, which is traditionally combined with the Shacharit in synagogues, is considered to be additional to the regular services of Shacharit, Mincha, and Maariv. In contemporary Hebrew, the word may also signify a newspaper supplement. During the days of the Holy Temple, additional offerings were offered on these festive days. Mussaf is now recited in lieu of these offerings.
