Transit Chart Calculator — The Sky Today, Against Your Chart

A transit chart is a snapshot of the sky at a chosen date: the position of each planet in the tropical zodiac on that day, laid over your natal chart (the sky at your birth). This calculator shows all ten bodies — the seven classical planets plus Uranus, Neptune and Pluto — for the date you pick, and which of them are making conjunctions, sextiles, squares, trines or oppositions to your natal planets.

Every aspect has an orb: the gap, in degrees, between its actual angle and the exact angle (a square is exactly 90°, an opposition exactly 180°, and so on). When the gap is still closing — the transiting planet is still approaching the exact aspect — the aspect is called applying. Once the exact angle has been passed, it is separating. At orb zero the aspect is exact: neither applying nor separating.

Two parts. The positions table lists all ten bodies — Sun through Pluto — with their tropical sign, degree and retrograde status on the date you chose; there are no houses, because transits are not bound to the natal ascendant. Below it, the natal-contacts list shows every transit planet making a conjunction, sextile, square, trine or opposition to a natal planet, sorted from the smallest orb to the largest, with each aspect labeled applying or separating.

Because what it computes is geometry: where the planets are, and how they stand to your birth chart, on one date. Whether that geometry means a specific event for you is a matter of interpretation, and this calculator deliberately stays on the geometry side. Interpreting transits for your own decisions is the work of a consultation with a trained astrologer.

Gochar is the Vedic word for transits — the same underlying idea of comparing the sky now against the birth chart — but it is computed in the sidereal zodiac (with the Lahiri ayanamsa) and read with Vedic techniques. This tool computes the tropical version, which Western astrology uses. The two zodiacs are offset by about 24 degrees, so on the same day a planet can sit in different signs in the two systems — they are different systems, not two names for the same result.

The date field defaults to today and is editable — pick any past or future date you like, and the positions are computed for exactly that day. The tool computes one date per request; it does not scan a range of dates for 'important' transits.
