What Ayadi measures
The classical Vastu tradition judges a building not only by where its rooms sit but by the dimensions themselves. Ayadi works in the traditional units: one angula is three-quarters of an inch, and twenty-four angulas make one hasta. Length and breadth are converted to angulas separately, the perimeter is taken as twice their sum, and that perimeter is settled to a whole angula — the rounding mode is printed with the result, because it is a choice, not a tradition.
The six vargas
Each varga multiplies the whole-angula perimeter by its own factor and keeps the remainder on its own divisor. Aaya is read against Vyaya — income against expense — with a higher Aaya counted favourable and equality marked for review. Yoni names one of eight direction-linked types, the odd ones favourable. Varam lands on a weekday, Nakshatra on one of the twenty-seven lunar mansions, and Amsam on its own nine-fold cycle. Nakshatra is shown as neutral here, because a personal verdict needs birth data. The tool never compresses the six readings into one invented score.
Ayadi is not a single fixed formula across the classical Vastu tradition: some lineages work from the area rather than the perimeter, or substitute other vargas. This calculator follows one named profile and prints it, so a practitioner always knows exactly which convention produced the numbers.
How practitioners use this
The natural moment for Ayadi is the design stage, while length and breadth can still move. Practitioners test candidate dimensions, nudge a wall a few angulas, and re-run the six vargas until the readings sit well — then place the full varga table in the client report under their own name.
Frequently asked questions
Which units can I enter?
Feet, inches, metres, centimetres, hasta or angula — each is converted exactly, so thirty feet and thirty metres give different perimeters, as they should.
Does the tool give one pass-or-fail verdict?
No. It reports six readings with their individual status. A combined score would be an invention, so none is produced.
What if Aaya equals Vyaya?
The result is marked for review rather than forced to a side; the practitioner decides with the whole picture in view.
