Halachic Framework

Tenth of Tevet is a rabbinic fast day. Core rules:

  • Duration: The fast runs from dawn (alot haShachar) to nightfall (tzait haKochavim) — a shorter span than Yom Kippur's sunset-to-nightfall fast.
  • Exemptions: The ill, pregnant and nursing women, and young children are exempt. Anyone whose health would be at risk must not fast.
  • Liturgy: The Amidah includes the fast-day blessing "Aneinu," and Slichot (penitential prayers) are added. Tachanun is not said on the fast itself but is omitted afterward as well.

Customs & Observances

  • Fast from dawn until nightfall — observed even when it falls on a Friday
  • Reciting Selichot
  • General Kaddish and memorial prayers for Holocaust victims with unknown yahrzeit dates
