FAQ
Is Rahu Kaal really inauspicious?
Per traditional Hindu astrology — yes. Empirical studies show no measurable effect, but cultural practice is widespread. Many Indians avoid starting new ventures during Rahu Kaal.
Does Rahu Kaal apply to ongoing activities?
No — only to start of new ventures. Continuing existing work (eating, sleeping, working at job) is fine. The taboo is specifically on initiating something significant.
Is sunrise/sunset universal or city-specific?
City-specific. We use defaults, but for accurate Rahu Kaal, plug in your city's actual sunrise/sunset (timeanddate.com). Variation across India is up to 1.5 hours.
