Moed (Hebrew: מועד, pl. מועדים, *mo'adim*; lit. “appointed time” or “season”) is one of the six orders (*sedarim*) of the Mishnah and Talmud, the foundational texts of rabbinic Judaism. The order comprises tractates governing the laws of Shabbat, Jewish festivals, fasts, and other calendrically designated occasions. As a category, *moed* encompasses both the textual corpus treating these laws and the broader halakhic concept of sacred time as distinct from ordinary time.

Seder Moed consists of twelve tractates in the standard arrangement of the Mishnah, covering a range of subjects organized around the Jewish calendar. The tractates are:

• Shabbat - laws of the weekly day of rest
• Eruvin - laws of the eruv, a legal boundary permitting certain Shabbat activities
• Pesachim - laws of Passover and the Passover sacrifice
• Shekalim - the half-shekel Temple tax
• Yoma - the Yom Kippur service and fast
• Sukkah - laws of the Sukkot festival
• Beitzah (also called Yom Tov) - general laws of festival days
• Rosh Hashanah - the Jewish New Year and calendar regulation
• Ta'anit - laws of fast days
• Megillah - Purim observance and public Torah reading
• Moed Katan - intermediate festival days (Chol HaMoed) and mourning restrictions
• Chagigah - the pilgrimage festival sacrifice and purity laws

Both the Babylonian Talmud (*Talmud Bavli*) and the Jerusalem Talmud (*Talmud Yerushalmi*) contain Gemara for most tractates of Moed, though coverage varies between the two recensions.

Seder Moed is among the most extensively studied portions of rabbinic literature. Within traditional Jewish legal scholarship (*halakhah*), the tractates of Moed remain active areas of practical adjudication, particularly Shabbat and the festival laws, which continue to generate responsa literature addressing contemporary circumstances. Academic study of Moed draws on textual criticism, manuscript comparison, archaeology, and comparative ancient Near Eastern religion to situate the tractates historically and literarily.

The relationship between the Babylonian and Jerusalem Talmuds' treatments of Moed tractates - including differences in legal rulings, attributions, and editorial layers - is a subject of ongoing scholarly discussion. The dating and compositional history of the Mishnah itself, and the question of how earlier sources were redacted into the final text, remain active areas of inquiry.

• Traditional Orthodox view - The laws of Moed derive from Sinaitic revelation, both written (Torah) and oral (Oral Torah), transmitted without essential discontinuity through the rabbinic chain of tradition. Halakhic rulings in these tractates carry binding religious authority. moed-traditional-orthodox-viewpoint

• Conservative/Masorti view - The Moed tractates reflect authentic Jewish legal development with binding weight, interpreted through historical-critical awareness and the evolving needs of the community. moed-conservative-masorti-viewpoint

• Reform and Liberal view - Moed texts are historically significant expressions of Jewish communal life and ethics, but their specific ritual requirements are not uniformly binding; contemporary communities may adapt observance. moed-reform-liberal-viewpoint

• Academic historical-critical view - Seder Moed is a product of editorial compilation over several centuries, reflecting the concerns of rabbinic academies in Roman Palestine and Sasanian Babylonia rather than straightforward transmission of earlier practice. moed-academic-historical-critical-viewpoint

• The appropriate scope and limits of Shabbat law as addressed in tractate Shabbat has been a subject of sustained communal and legal dispute across Jewish denominations and in Israeli civil law. moed-shabbat-law-scope-controversy

• The authority and accuracy of the Jewish calendar system, rooted partly in Rosh Hashanah and Sanhedrin, has generated historical controversies including the Saadia-Ben Meir calendar dispute of 921-922 CE. moed-calendar-authority-controversy
