GET/v1/astro/panchanga/festivals

Hindu festival calendar

Compute all major Hindu festival dates for a given year and location. Returns 20 pan-Hindu festivals including solar sankrantis (Makar Sankranti, Vaisakhi) and tithi-based festivals (Diwali, Holi, Dussehra, Janmashtami, Ganesh Chaturthi, Ram Navami, and 12 others). All dates are astronomically computed — no hardcoded dates. Tithi festivals use the Sun-Moon elongation at local sunrise with Lahiri sidereal ayanamsa. Location is required for accurate sunrise-based tithi determination.
