Jupiter’s transit is read from your natal Moon sign, so an accurate birth time matters. Your birth details are used only to calculate — nothing is saved, and no account is needed.

What a Jupiter transit is

Jupiter — Guru, the great benefic — spends roughly a year in each sign, then moves on. That move is called Guru Peyarchiin Tamil, and it shifts the part of life Jupiter’s expansive, protective influence rests on for the next twelve to thirteen months. It is read from your natal Moon sign, the janma rasi.

Where classical astrology is precise is in where Jupiter lands relative to your Moon — and honest gochara treats that as a tendency, a season with a certain grain, not a promise of good or bad fortune.

The favourable and demanding houses

  • Favourable — Jupiter in the 2nd, 5th, 7th, 9th, or 11th from your Moon. The 11th (gains) is considered the most auspicious.
  • Demanding — Jupiter in the 1st, 3rd, 4th, 6th, 8th (Guru Ashtama), 10th, or 12th. These ask for patience and inner work rather than expansion.

How it’s calculated

The calculator finds your natal Moon sign from your birth details, then computes Jupiter’s real position todayand counts the house from your Moon. Because it uses Jupiter’s actual current longitude — not a mean-motion estimate — the transit sign is exact even in the days right around an ingress, when it matters most.

Frequently asked questions

What is a Jupiter transit (Guru Peyarchi)?

Guru Peyarchi is the moment Jupiter (Guru) changes signs, which it does roughly once every 12–13 months. Because Jupiter is the great benefic of expansion and wisdom, its move into a new sign shifts the area of life it supports for the next year, read from your natal Moon sign (janma rasi).

How is the Jupiter transit result calculated?

Find your natal Moon sign, then count which house Jupiter's current sign falls in from that Moon. Jupiter is classically auspicious when transiting the 2nd, 5th, 7th, 9th, and 11th from the Moon, and more demanding in the 1st, 3rd, 4th, 6th, 8th, 10th, and 12th. This calculator computes Jupiter's real current position, so the transit sign is exact even right at ingress.

Which Jupiter transits are considered good?

Classically, Jupiter transiting the 2nd (wealth and family), 5th (children, learning, creativity), 7th (partnership), 9th (fortune and dharma), and 11th (gains) from your Moon is favourable. The 11th is regarded as the most auspicious. These are tendencies, not guarantees — the actual effect depends on Jupiter's strength and your running dasha.

What is Guru Ashtama?

Guru Ashtama is Jupiter transiting the 8th house from your natal Moon — classically a sensitive period associated with obstacles, anxiety, and unexpected expense. Like the rest of gochara, it's a tendency to work with consciously, not a sentence of misfortune.

Is a Jupiter transit the same as Guru Peyarchi?

Yes. 'Guru Peyarchi' is the Tamil term for Jupiter's transit — 'Guru' is Jupiter and 'peyarchi' means the change of sign. The calculation and meaning are identical to the Jupiter transit read from your Moon sign.
