The word Panchang is derived from two Sanskrit roots: Pancha (five) and Anga (limb). It represents five distinct astronomical dimensions that together describe the energetic texture of any given moment in space-time.
The first limb is Tithi, the lunar day. Unlike a standard civil day that runs from midnight to midnight, a Tithi is defined purely by angular geometry: it is the precise duration required for the Moon to advance exactly twelve degrees of celestial longitude ahead of the Sun. Because the Moon moves along an elliptical orbit with variable velocity, a Tithi can range anywhere from nineteen to twenty-six hours. It governs the inner emotional and hormonal tides of the body.
The second limb is Vara, the planetary solar day of the week, linking each twenty-four hour cycle to one of the seven visible cosmic rulers. The third is Nakshatra, the lunar mansion: one of twenty-seven equal divisions of the ecliptic that the Moon traverses every month, reflecting the archetypal subconscious frequency of the day.
The fourth is Yoga, the combined angular sum of solar and lunar longitudes, divided into twenty-seven qualitative periods indicating harmonizing or challenging subtle energies. The fifth is Karana, half of a Tithi, providing granular insight into the capacity for physical work, negotiation, and domestic endeavor.
