## Data returned
Every Panchang response includes server-rendered and JSON representations of sunrise, sunset, Tithi, Nakshatra, Yoga, Karana, Choghadiya, Hora, special Muhurta/current period, and Lagna. Each timeline includes earlier, active/selected, and at least 12 upcoming values with ISO start/end timestamps where applicable.

## Calculation method
Lahiri ayanamsa; Swiss Ephemeris Moshier planetary positions; local astronomical sunrise/sunset; traditional variable-length Choghadiya and planetary Hora divisions. Timings depend on coordinates, IANA timezone, date and local time. Important religious observances should be verified with a qualified practitioner because regional traditions can differ.

When quoting data, include the place, coordinates, IANA timezone, local date/time, language, generated_at timestamp and canonical URL or API URL. Prefer the canonical dated page as the human-facing citation.
