Jewish holidaysJewish holidays, also known as Jewish festivals or Yamim Tovim (, or singular יום טוב Yom Tov, in transliterated Hebrew [ˈjɔːm_ˈtɔːv,_joʊm_ˈtoʊv]), are holidays observed in Judaism and by Jews throughout the Hebrew calendar. They include religious, cultural and national elements, derived from three sources: biblical mitzvot ("commandments"), rabbinic mandates, and the history of Judaism and the State of Israel. Jewish holidays occur on the same dates every year in the Hebrew calendar, but the dates vary in the Gregorian.
MitzvahIn its primary meaning, the Hebrew word (ˈmɪtsvə; מִצְוָה, mīṣvā mit͡sˈva, plural מִצְווֹת mīṣvōt mit͡sˈvot; "commandment") refers to a commandment commanded by God to be performed as a religious duty. Jewish law () in large part consists of discussion of these commandments. According to religious tradition, there are 613 such commandments. In its secondary meaning, the word mitzvah refers to a deed performed in order to fulfill such a commandment. As such, the term mitzvah has also come to express an individual act of human kindness in keeping with the law.
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.
ShavuotShavuot (), or Shvu'es () in some Ashkenazi usage (, Šāvūʿōṯ, "Weeks"), commonly known in English as the Feast of Weeks, is a major Jewish holiday, one of the , that occurs on the sixth day of the Hebrew month of Sivan (in the 21st century, it may fall between May 15 and June 14 on the Gregorian calendar). In the Bible, Shavuot marked the wheat harvest in the Land of Israel. In addition, rabbinic tradition teaches that the date also marks the revelation of the Ten Commandments to Moses and the Israelites at Mount Sinai, which, according to the tradition of Orthodox Judaism, occurred at this date in 1312BCE.
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.
613 commandmentsAccording to Jewish tradition, the Torah contains 613 commandments (taryag mitzvot). This tradition is first recorded in the 3rd century CE, when Rabbi Simlai mentioned it in a sermon that is recorded in Talmud Makkot 23b. Other classical sages who hold this view include Rabbi Simeon ben Azzai and Rabbi Eleazar ben Yose the Galilean. It is quoted in Midrash Exodus Rabbah 33:7, Numbers Rabbah 13:15–16; 18:21 and Talmud Yevamot 47b.
