Ephemeris Research

Conjunctions, aspects and sign changes. Ask in plain words.

Panchang and festival dates calculated by Pandit Mahesh Shastri, Panchangakarta and Siddhanti, using Drishya Ganita and traditional Dharmashastra principles.

Research, not prediction.·Sidereal Lahiri·mean nodes·searches from year 1 to 3000, up to 20 years at a time·precomputed reference tables cover 1900 to 2500 Vedic relations are by sign. Rashi-yuti across a boundary needs both planets within 5° of the shared edge; drishti can also count a planet near a sign edge (changeable).

Planets and relation

First planet Relation Second planet

Sign, nakshatra and pada changes use the first planet only.

Ucca / Nica and latitude conjunction

Ucca / Nica crossings Only within this many degrees of longitude (optional)

Ucca / Nica: choose one of the seven grahas as the first planet, or "Any planet" for all seven. Latitude conjunction: choose two planets; the Moon is allowed here.

Planet group

Planets in the group (leave all unticked for the seven grahas):

Sun Moon Mars Mercury Jupiter Venus Saturn Uranus Neptune Pluto Rahu (mean) Ketu (mean)

Largest spread, in degrees Gathering: grouped by Gathering: at least this many planets

How spread and gathering work

Spread: when every chosen planet fits inside an arc this wide, with the exact start, the tightest moment and the end. Gathering: when at least that many of the chosen planets share a rashi, or fit inside the arc; each set of planets is its own row. Rahu and Ketu are optional; choose one of them, not both. These are mathematical groupings: no classical name is given.

Navamsa and nakshatra

Motion Only in this nakshatra (optional) Two planets together in the same D1 and D9 at this date (blank: now) and time (in the zone below)

How these searches work

Navamsa changes, Vargottama periods, nakshatra and pada stays: choose one planet, or "Any planet" for the nine grahas. Every boundary moment is solved exactly, including the backward crossings of a retrograde loop. "Retrograde only" keeps backward navamsa crossings, and the nakshatras or padas a planet re-enters in a retrograde loop. The nakshatra choice applies to nakshatra and pada stays. Same nakshatra or pada: choose two planets. D1 and D9: the nine grahas at one moment; the date and time are read in the time zone chosen below.

Entry into a sign or nakshatra

Only when it enters (optional)

Graha yuddha (planetary war)

Mars, Mercury, Jupiter, Venus and Saturn. Leave a planet as "any" to search every pair. The orb defaults to 1 degree. The victor is the planet farther north in ecliptic latitude (Surya Siddhanta / Brihat Samhita tradition); longitude only establishes that the war takes place. Each result has a "Show geometry" panel with the full positions, brightness and disc sizes.

Disc model for the encounter type Encounter type

Both models use the same Swiss Ephemeris positions, exact times and latitude victor; the model changes only the planet disc sizes and the encounter type (Surya Siddhanta 7.12-7.22). The SS model is a hybrid reconstruction (the text's bimba sizes with modern distances), not a historically exact Surya Siddhanta calculation. The two models' disc sizes are never mixed.

Retrograde or direct at the meeting

Which planets are retrograde "Near a station" means within

Judged at each exact meeting; an approach with no exact meeting is judged at its closest day.

Rashi-yuti and graha drishti

Sign-edge tolerance (boundary) If Rahu or Ketu is one of the planets, it aspects Or your own aspect houses for both planets (e.g. 5,9)

Period and time zone

Show From year To year Show times in Orb in degrees, 1 to 8 (optional)

Any year from 1 to 3000. Up to 20 years at a time. Sign in with Google (top right) to search up to 100 years.

How the orb works

Orb: leave blank for the default (5° for degree-based relations, none for Vedic). For rashi-yuti, the orb (or the sign-edge menu above) is the Boundary-Spanning Yuti tolerance: two planets in adjacent signs count only when both are within this many degrees of the boundary they share. For drishti, it keeps the older exploratory sign-edge rule: a planet within this many degrees of a sign edge also counts in the neighbouring sign.
