The Five Sacred Limbs (Pancha-Anga)
Panchanga literally translates to the "Five Limbs" of time that govern cosmic vitality and human biorhythms in classical Vedic astrology (Jyotisha). GrahaNova evaluates all five limbs dynamically:
1. Tithi (Lunar Phase)
Governed by Venus (Jala Tatwa). Measures the exact 12-degree elongation difference between Moon and Sun across Shukla and Krishna Paksha.
2. Vara (Solar Weekday)
Governed by Mars (Agni Tatwa). Identifies the planetary ruler of the solar day from local sunrise to next sunrise.
3. Nakshatra (Lunar Mansion)
Governed by Saturn (Vayu Tatwa). Pinpoints the 13°20' sector of the zodiac currently occupied by the Moon and its active Pada.
4. Yoga (Angular Confluence)
Governed by Jupiter (Akasha Tatwa). Measures the sum of solar and lunar Nirayana longitudes to classify one of the 27 classical Yogas.
5. Karana (Half-Tithi)
Governed by Mercury (Prithvi Tatwa). Represents half of a Tithi (6 degrees), categorizing actions by movable (Chara) or fixed (Sthira) energy.

Astronomical Kalam Windows
GrahaNova computes daily inauspicious and auspicious solar-proportional segments based on actual local sunrise and sunset across 82,000+ cities:
- Rahu Kalam: Daily 1.5-hour inauspicious window ruled by Rahu. Major new beginnings and agreements are classically avoided.
- Yamagandam: Inauspicious window ruled by Ketu/Yama, unsuitable for vital travels or ceremonial commencements.
- Gulika Kalam: Auspicious window ruled by Gulika/Mandi where deeds take permanent roots.
- Abhijit Muhurtha: The supreme mid-day auspicious window that destroys all minor afflictions (doshas).
