गोचर
Current or selected graha positions counted from a natal Moon or Lagna reference.
Calculate Gochara positions from natal Moon and Lagna, including sidereal transit rashis, whole-sign counts, same-rashi contacts, and Graha Drishti.
Gochara needs both a natal chart and a selected transit instant.
The natal Moon is a classical primary reference; Samvat also reports whole-sign houses from natal Lagna.
A transit position or relationship is a calculated fact, not by itself a favorable or unfavorable outcome.
Counting from the natal Moon answers which whole-sign position a moving graha occupies from Chandra Rashi. Counting from natal Lagna answers which natal whole-sign house contains that transit.
Samvat displays both counts separately. It does not silently replace one reference with the other or combine them into a score.
For the chosen instant, calculate Lahiri sidereal positions for the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, and mean Rahu and Ketu. Each result includes rashi, degree, motion, house from Lagna, and count from Moon.
The selected time uses the birthplace timezone in the calculator so the visible civil time maps to one exact UTC instant.
A same-rashi contact occurs when a transit graha and natal graha occupy the same sidereal rashi. Graha Drishti is calculated separately as a directed full aspect from the transit graha to the natal position.
The v1 Gochara result does not apply Vedha, Ashtakavarga, Dasha synthesis, strength scoring, or outcome interpretation.
The transit rashi is counted inclusively from the natal reference rashi.
house from reference = ((transit rashi - reference rashi + 12) mod 12) + 1Interpretive claims require additional traditional rules and context; this calculation intentionally stops at position and relationship evidence.
The encoded rules are tied to these cited passages.
Use these as working patterns when reading Panchang details or planning around Hindu dates.
You want to compare today with a date six months ahead.
The comparison is based on two explicit sky states rather than a generic sign forecast.
The result says transit Saturn casts its 10th Drishti to natal Venus.
The relationship can be reconstructed from the displayed rashi positions and rule.
A Gochara engine should first answer where the grahas are and how those positions relate to the natal chart.
Samvat keeps that evidence visible and leaves outcome-oriented prediction outside the product scope.
Gochara is the calculation of moving graha positions for a selected time in relation to a natal reference, commonly the natal Moon and also the natal Lagna.
Classical Gochara gives the natal Moon an important reference role. Samvat reports both the inclusive count from natal Moon and the whole-sign house from natal Lagna.
No. A position or aspect is a structural chart fact. Outcome interpretation requires additional rules and context that Samvat does not provide.
Yes. The Samvat calculator accepts a selected transit date and time within the supported 1900 to 2100 calculation range.
