Acharei Mot, Aharei Mos, or Ahare Moth or Acharei (אַחֲרֵי מוֹת or אַחֲרֵי — Hebrew for "after the death" or "after," the fifth and sixth words or the fifth word, and the first distinctive word or words, in the parashah) is the 29th weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading and the sixth in the Book of Leviticus. The parashah sets forth the law of the Yom Kippur ritual, centralized offerings, blood, and sexual practices. It constitutes Leviticus 16:1–18:30. The parashah is made up of 4,294 Hebrew letters, 1,170 Hebrew words, and 80 verses, and can occupy about 154 lines in a Torah Scroll (סֵפֶר תּוֹרָה, Sefer Torah).
Jews generally read it in April or early May. The lunisolar Hebrew calendar contains up to 55 weeks, the exact number varying between 50 in common years and 54 or 55 in leap years. In leap years (for example, 2019, 2022, 2024, and 2027), parashah Acharei Mot is read separately on the 29th Sabbath after Simchat Torah. In common years (for example, 2017, 2018, 2020, 2021, 2023, 2025, 2026, and 2028), parashah Acharei Mot is combined with the next parashah, Kedoshim, to help achieve the needed number of weekly readings.
