Astronomical precision for Panchang calculations.
Vittix Vedic Panchang uses timezone-aware astronomy, consistent ayanamsa, and proven sunrise and moon algorithms to deliver reliable Hindu calendar output for modern PHP applications.
Astronomical basis
Ephemeris and calculation methods
The package builds daily Panchang results from astronomical positions rather than fixed lookup tables. This ensures that tithi, nakshatra, yoga, and calendar output remain accurate across timezones and historical dates.
- • Ephemeris-derived solar and lunar longitudes
- • Sunrise and sunset computed per timezone
- • Moonrise and moonset from lunar position algorithms
Ayanamsa
Using a consistent sidereal reference
The library supports the Lahiri ayanamsa system and other widely accepted sidereal references for Vedic calculations. This makes the output reliable for festival rules and muhurta windows.
- • Lahiri Ayanamsa support
- • Accurate sidereal longitudes for tithi and nakshatra
- • Consistent results for traditional calendar events
Timing and validation
Timezone, DST, and historical accuracy
All calculations respect local timezone offsets and daylight saving time rules for location-aware Panchang results.
The engine can compute calendar data for past years, making it suitable for archives, festival lookup, and retrospective queries.
Moonrise, moonset, and lunar phase calculations are derived from astronomical positions to align with traditional Panchang rules.
The package is designed for measurable output and can be validated against established Panchang sources and festival rules.
Supported range
Broad date and time coverage
Vittix Vedic Panchang is built to support modern application requirements across current and historical periods, with timezone-correct Panchang outputs and festival calculations that adapt to local rules.
