Vedic Astrology Calculators
Individual classical calculations, each with a working form and a worked example. All of them come out of the same engine as the full birth chart.
Some of these are the questions people look up one at a time — a Moon sign, a navamsa, a dosha check. Others usually stop at a textbook page or a desktop-only Windows program. Most take a birth date, time and place, and the matching checks take two birth stars or two Moon signs; each runs the real computation and shows you the output with an explanation of how to read it. If you want them all at once for a single chart, start with the free birth chart instead — nearly every calculation below is one of its panels.

Why these pages exist
Every page is a real calculation, not an article with a form bolted on. For several of them the best result a search returns today is a scanned PDF, a video about doing the arithmetic in a spreadsheet, or an instruction to install a Windows program; for the familiar ones, it is usually a sign name with no working shown. Here the method, the engine's output and the convention behind it are all on the page.
Each page carries the classical definition, the method, a worked example with real numbers, and the honest limits of what the figure can tell you. None of them is a prediction, and none of them is a substitute for reading the whole chart.
Every calculation at once
The free birth chart is the whole engine for one set of birth details. Each view below is a panel of it, and each one has its own address, so you can link straight to the part you want.
