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.
