Vara (Weekday) Calculation — Perimeter×9÷7

Varanasi Sthapati guilds maintain Graha-vara compatibility tables that cross-reference the building's Vara result with the owner's Janma-vara (birth weekday). Rajasthani Silawat masons inscribe the Vara day-name alongside the Nakshatra symbol on the foundation stone — these paired inscriptions survive on havelis in Jaisalmer dating to the 16th century.

Peshwa-era Wadas in Pune show plinth-dimension adjustments targeting the Vara remainder specifically — the Sutradhar micro-adjusted the outer wall by 1-3 cm to shift a Mars or Saturn result to a benefic weekday. The Marathi Sthapati tradition uniquely assigns Mercury (Wednesday) the highest residential Vara ranking, associating Budha-vara with Vyapara-vriddhi (trade prosperity).

Tamil Sthapatis of the Vishwakarma community in Kumbakonam calculate the Vara to half-Angula precision, yielding the most accurate weekday determination in any Indian tradition. The Tamil Siddha medical tradition uniquely extends the Vara concept to hospitals and clinics — Monday (Chandra-varam) is specifically prescribed for healing structures, linking the Moon's cooling nature to patient recovery.

Kakatiya guild record stones at the Warangal Thousand-Pillar Temple contain Vara remainder tables carved in Telugu numerals alongside Nakshatra tables — among the oldest physical evidence of the weekday calculation system. Telugu Sthapatis uniquely rank Thursday (Guru-varam) as the supreme residential Vara, associating Jupiter's lordship with Vidya-vriddhi (growth of knowledge).

Jain Basadis at Mudabidri contain inscribed Vara results in Halegannada numerals on pillar bases — the Sthapati recorded the weekday day-lord as part of the mathematical certification of the structure. The Hoysala-Jain tradition uniquely ranks Friday (Shukra-vara) as the supreme residential Vara, associating Venus with Ahimsa (non-violence) and Griha-sukha (domestic happiness).

The Perumthachan lineage maintained secret Vara-Nakshatra compatibility tables in their Ganita-grantha — cross-referencing the building's weekday day-lord with the owner's Janma-nakshatra to ensure double astrological compatibility. The Manushyalaya Chandrika uniquely prescribes that if the Vara yields Saturday (Shani), the Thachan must not merely perform a remedy but must physically adjust the perimeter before announcing the result.

Solanki-era Havelis in Patan contain Vara day-lord names inscribed in Gujarati script on the courtyard foundation alongside the Ayadi results — visible proof that the weekday calculation was performed. The Gujarati Jain tradition uniquely rejects Mars (Tuesday) Vara on Ahimsa grounds — Mars's martial nature is incompatible with the Jain ideal of non-violent domestic space.

Bengali Sutradhar guilds of Nabadwip uniquely prioritise Monday (Soma-var) as the supreme residential Vara, linking the Moon's lordship to the Shakta tradition's Chandra-puja for mental peace. The Ganaka announces the Vara result during the Bhoomi Puja while the Purohit performs parallel Graha-mantra recitation — a dual mathematical-ritual validation of the planetary weekday unique to Bengal.

The Jagannath Temple at Puri is traditionally cited as yielding a Thursday (Guru-vara) Vara result — Jupiter's lordship over the supreme Odia temple exemplifies the ideal planetary weekday for religious architecture. Kalinga Sthapatis uniquely maintain separate Vara tables for temple, residential, and commercial structures, with different auspiciousness rankings for each building type.

Punjabi Raj-Mistri guilds maintained Vara tables in their Ganit-pothi calibrated to the Punjabi Gaz (yard measure). The Sikh tradition uniquely frames the Vara calculation as an expression of Hukam — accepting the planetary result with equanimity while still taking diligent action to ensure auspiciousness. Golden Temple renovations historically included Vara verification as part of Seva.
