Your birth details

Birth date

Birth time (local, where you were born)

Precise birth time isn't important here — Jupiter and the Sun move slowly, so the time only shifts a window's edge by a day at most. A rough time (or noon) is fine.

Upcoming lucky windows

100% — both transit Jupiter & the Sun are in your birth-Venus sign. 75% — both are in signs of the same element as your birth Venus. 50% — each is in a same-element or opposite sign (≥1 opposite). Casual — non-serious: each is in a same-element, opposite or 3/11 sign (≥1 in 3/11).
☾ A Moon line marks the date within a window when the fast-moving Moon is also in a same-element sign as your birth Venus — extra timing info only, not part of the score.
Here “birth Venus” is your reading anchor — birth Mars for women (the BNN spouse-significator) unless you opt to use Venus. Dates are approximate (±~1 day) and based on the Lahiri ayanāṁśa.

How this works & the method

This tool uses sidereal (Vedic) positions with the Lahiri ayanāṁśa, as used in Bhrigu Nandi Nadi (BNN). Your reading anchor — birth Venus for men, or birth Mars for women (the BNN husband/spouse-significator) — has its sign and element computed, then the live transits of Jupiter and the Sun are checked against it. (Below, "birth Venus" means whichever anchor applies. Women may tick the option to use Venus instead of Mars, which some practitioners find more accurate.)

100% lucky — when transit Jupiter and the Sun are both moving through the same zodiac sign as your birth Venus.
75% lucky — when transit Jupiter and the Sun are both in signs of the same element (fire, earth, air or water) as your birth Venus.
50% lucky — when transit Jupiter and the Sun are each in a same-element sign or the sign exactly opposite your birth Venus (180° away, e.g. Gemini ↔ Sagittarius), with at least one in the opposite sign.
Casual (non-serious) — when transit Jupiter and the Sun are each in a same-element, opposite, or 3/11 sign (the 3rd or 11th sign from your birth Venus), with at least one in a 3/11 sign. A classic Nadi marker of light, non-serious connections.
Otherwise the window is not considered specially favourable by this rule.
Moon (☾) — extra info, not scored. Within each window we also note the date the fast Moon enters a same-element sign as your birth Venus — a handy "best day" pointer. It never changes the percentage.

The 12 signs by element — Fire: Aries, Leo, Sagittarius · Earth: Taurus, Virgo, Capricorn · Air: Gemini, Libra, Aquarius · Water: Cancer, Scorpio, Pisces.
