Panchang Calendar Sunrise API

Panchang Calendar Sunrise

The Panchang Calendar Sunrise API generates a full month-view Panchang almanac where every daily entry is computed relative to the astronomical sunrise of that day at the given location. This is the sunrise-anchored counterpart to the standard Panchang Calendar endpoint, and it delivers the most traditionally precise form of the monthly Hindu almanac — the method followed in classical Vedic astrology and orthodox religious practice.

What This API Does

This endpoint calculates the complete set of Panchang elements for every day of the specified month and year, with all values anchored to the actual local sunrise at the provided latitude, longitude, and timezone. Because the Hindu day (Tithi) begins and ends at sunrise rather than midnight, tying calculations to sunrise produces results that are in strict accordance with traditional Panchang methodology. The Ayanamsha used for sidereal calculations is selectable via a request header.

Data Returned

For each day in the requested month, the response typically includes:

• Tithi — The lunar day name, index, and presiding deity, computed from sunrise

• Nakshatra — The lunar mansion occupied by the Moon at sunrise, with ruling deity

• Yoga — The daily auspiciousness index derived from the combined solar and lunar longitudes at sunrise

• Karana — The half-tithi unit in effect at sunrise

• Vara — The weekday and its planetary lord

• Sunrise & Sunset times — Precise astronomically computed local sunrise and sunset for each date and location

• Moonrise & Moonset times — Daily lunar rise and set timings

• Festivals and observances — Hindu festivals, Vrats (fasting days), and religious events for each date

• Chandra Rashi — The zodiac sign occupied by the Moon

• Rahu Kalam, Gulika Kalam, Yamaganda — Inauspicious daily time windows

• Abhijit Muhurta — The most auspicious time slot of the day

• Ayanamsha value — The sidereal correction applied per the selected system

Main Use Cases

• Traditional Hindu calendar apps — Building monthly Panchang calendar views that strictly follow the sunrise-based day boundary, as used in orthodox almanacs and Panchangams

• Religious and ritual scheduling — Helping priests, practitioners, and devotees identify auspicious and inauspicious days across an entire month using sunrise-accurate data

• Vedic astrology platforms — Supplying a month-level, sunrise-anchored Panchang feed for horoscope, muhurta, and electional astrology features

• Festival discovery — Surfacing the correct dates for festivals and Vrats that depend on the Tithi at sunrise (e.g., Ekadashi, Pradosh, Purnima)

• Muhurta and event planning tools — Enabling users to scan a full month for the best days and time windows for weddings, travel, business, or other significant activities

Key Functionality

• Sunrise-anchored daily calculations — All Panchang elements for each day are computed from the actual astronomical sunrise at the specified location, matching the traditional Vedic definition of a day and ensuring orthodox accuracy

• Full-month coverage in one call — Returns data for every day of the specified month in a single request, avoiding the overhead of repeated per-day API calls

• Location-aware — Uses latitude, longitude, and timezone offset to derive precise sunrise times and location-specific Panchang values for any place in the world

• Configurable Ayanamsha — The X-Ayanamsha header allows selection of the sidereal correction system (e.g., Lahiri, Raman, KP), making the endpoint compatible with multiple Vedic astrology traditions

• Multi-language support — The Accept-Language header enables responses in the preferred regional or vernacular language, supporting diverse user bases

• Time-of-day input — Accepts hour, minute, and second in addition to month and year, allowing fine-grained anchoring for edge cases where the sunrise moment is near a Tithi or Nakshatra boundary
