Panchak is the period when the Moon moves through the final stretch of the zodiac — from the second half of Dhanishtha through Shatabhisha, Purva Bhadrapada, Uttara Bhadrapada and Revati (Aquarius–Pisces). Certain activities are traditionally avoided during Panchak. The weekday of birth names the type: Roga, Raja, Agni, Chor or Mrityu Panchak.
