Rahu Kalam

Rahu Kalam (or Rahukalam) is a specific window of time every day that many Vedic traditions consider inauspicious for kicking off important new work, starting a journey, or beginning a major ceremony. As the name suggests, it is astrologically associated with the malefic influence of Rahu. Interestingly, it is not a fixed clock time! We take the daytime (from sunrise to sunset) and divide it into eight equal parts. One of those parts is designated as Rahu Kalam for that specific weekday—so the actual window shifts depending on your local sunrise, sunset, latitude, and timezone. Key points: • What to postpone: It's generally advised to avoid new ventures, major decisions, starting journeys, and ritual beginnings during this window. • Why we track it: Rahu is treated as a malefic shadow planet, and its period is seen as generally unfavorable for auspicious starts. • How it's calculated: The day-length (sunrise to sunset) is split into eight segments; the segment that becomes Rahu Kalam follows a fixed weekday rule. • Varies every day: The exact wall-clock time changes every day because the sunrise and sunset times shift the segment boundaries. • Location matters: Even on the exact same date, a different city will have entirely different Rahu Kalam times!
