Rule used: Kartika Krishna Chaturthi — fasting day when Chaturthi prevails at local sunrise. Moon sighting for parana is local and not computed here.

Parana depends on local moonrise; Daanyam does not yet compute moonrise times. Use Panchang for moonrise in your city.

How these timings are calculated

Calculated using Daanyam's stated Panchang convention: Smarta purnimanta month labels, tithi sampled at local sunrise (Pradosh festivals use local sunset). India anchor dates use Delhi coordinates (28.6139°N, 77.209°E). Diaspora cities use catalog coordinates and IANA timezones including daylight saving where applicable.

Ephemeris: astronomia (sync) with Lahiri ayanāṃśa for nakshatra; Astro Engine when enabled for month strips.

Sunrise/sunset: NOAA-style solar approximation at observer coordinates.
