Why five limbs
The Sanskrit name itself states the architecture: pañca, five, and aṅga, limb. A traditional day is not compressed into a universal good or bad label. It is examined through five simultaneous temporal measures whose relationship changes continuously.
Grahvani’s Panchanga suite is designed to make these dimensions legible together and to preserve the local astronomical context in which they arise.
Tithi and karaṇa
Tithi measures the angular relationship of Sun and Moon in thirty lunar phases. It does not align neatly with the civil midnight-to-midnight day and can begin or end at any local clock time.
Karaṇa is a half-tithi division. Its shorter rhythm becomes especially relevant when a practitioner examines the exact portion of a day rather than treating the whole date as uniform.
Vāra
Vāra is the weekday under its planetary ruler. In the traditional frame, the day is related to local sunrise rather than merely the midnight boundary of a digital calendar.
The weekday supplies one quality among several. It may support an activity while another limb or event-specific rule demands caution.
Nakṣatra and yoga
Nakṣatra identifies the lunar mansion occupied by the Moon and brings its own symbolic, directional and activity-related vocabulary. Yoga is computed from the combined longitudes of Sun and Moon and divides that sum into twenty-seven parts.
Both change independently of the civil date. Their exact transition times are part of the practical information a real calendar or muhūrta workflow must expose.
From daily calendar to electional judgment
The five limbs provide the temporal fabric, but a muhūrta judgment adds the nature of the act, exclusions, local conditions and the chart of the chosen moment. Panchanga is therefore necessary but not sufficient for every election.
A mature interface helps the user move from today’s time landscape into the specialised question without pretending that one favourable limb settles the whole decision.
THE GRAHVANI PRINCIPLEPanchanga is a five-dimensional grammar of the day. Each limb describes a different relationship within time, and their transitions belong to an actual place.
