Mukesh Ambani is an Aries; his Moon falls in Sagittarius or Capricorn, as the missing hour decides, and his rising sign cannot be named, since no record, biography or statement by Ambani gives his birth hour. Wikidata gives the date, April 19, 1957, citing Britannica and the Munzinger archive, and in a 1998 Rediff interview Ambani named Aden as his birthplace. AstroSage lists 7:53 PM, the only hour found, crediting an astrology book not seen here. With only the date known, the chart's day runs midnight to midnight on Aden standard time (UTC+3).

At any hour, Venus stayed 1°07′ to 1°22′ from the Sun, combust, as in about one chart in 8 born in the 1950s, and the Sun was exalted in Aries, true of about one chart in 12 in the same ten years.

Sagittarius or Capricorn: the Moon's sign turns at 12:07 PM

The Moon ran from 23°35′ Sagittarius at the opening midnight to 6°10′ Capricorn at the closing one, entering Capricorn at 12:07 PM, so Sagittarius holds 51% of the day. A split date like this turns up in about 44% of charts born in the 1950s. Tradition makes Capricorn the Moon's detriment and Sagittarius neutral ground, so the hour changes its condition as well as its sign; the disseminating phase spans both halves.

Aden's near-equator horizon, sign by sign

At Aden's latitude the signs rose at fairly even speeds: Aries and Pisces in 1 hour 40 minutes apiece, Cancer and Sagittarius in 2 hours 11 minutes, with Capricorn rising at both midnights. The AstroSage hour falls between 6:12 PM and 8:20 PM, while Scorpio was rising, but no record or statement backs it, so the page draws no houses. The Sun was up from 5:45 AM to 6:12 PM, leaving a day or night birth, and so sect, open too.

How the 1950s sample ranks this date

Of the nine ranked here, the exalted Sun is scarcest among simulated 1950s births, yet combust Venus heads the list, since the score gives combustion a heavier set weight before scarcity is applied. The two are one conjunction seen from both sides: in traditional terms, the Sun strong in its exaltation and Venus hidden by its rays.

Venus changes sign inside the Sun's glare

Besides the Moon, only Venus changed sign, leaving Aries, its detriment, for Taurus, a sign it rules, at 6:28 AM. It stayed combust throughout, though too far from the Sun for cazimi. At the closing midnight the Sun still lacked 0°28′ of reaching Taurus, so its exaltation in Aries survives any hour.

Mars, starting the date at 20°05′ Gemini, held a declination of 24°20′ to 24°23′ north, above the Sun's 23°26′ ceiling all day, out of bounds like about one chart in 6 from the decade; declination-minded astrologers read that as acting outside the usual rules. Jupiter, retrograde from 23°11′ Virgo back to 23°06′, is in its detriment (about one chart in 5). Retrograde Jupiter turns up in 30% of 1950s charts, and retrograde Saturn, starting at 13°46′ Sagittarius, in 38%. Mercury moved slowly, Mars swiftly, and none of the four retrograde planets changed direction that day.

Each planet at the local midnight opening and closing April 19, 1957 in Aden; the Moon and Venus are the two that changed sign.

A Sun–Moon trine that slipped out of sign

The Sun and Moon kept a trine all day, as in about one chart in 10 born in the 1950s. The orb began at 4°56′, was exact in mid-morning and ended at 6°39′, by then joining Aries to Capricorn, a trine by degree only. Two T-squares held throughout, the Sun and Venus each opposing Neptune with Uranus square to both. A birth before 10:57 AM would add a third: the Moon opposite Mars, both square Jupiter. Until 9:22 PM the Moon also trined Pluto, which closed two grand trines, one with the Sun and one with Venus.

Closest databank charts share only the Aries Sun

Emma Watson's chart comes first among the four nearest pages, then Rodrigo Duterte's, B. R. Ambedkar's and Heath Ledger's. Only the Aries Sun can match by sign, since the Moon's is split and the rising sign unknown, so planetary longitudes set the order. No second databank entry carries this birth date.

In the Lahiri zodiac the Moon sign is settled

Once the Lahiri offset of 23°15′ comes off, Ambani's Moon runs from 0°20′ to 12°55′ of sidereal Sagittarius, so Jyotish gets a fixed Moon sign at any hour. The Sun stays in Aries and Venus never leaves it; Mars, Jupiter and Saturn each slip back one sign, to Taurus, Leo and Scorpio.

Saturn's second return overlapped Jupiter's fifth

Transiting Saturn reached its noon position of the birth date on December 17, 1986, 29.7 years on, and again in three passes from January 27, 2016 to October 25, 2016, while Jupiter's fifth return ran from December 31, 2015 to August 6, 2016. With noon standing in for the hour, Jupiter's first two passes, 15 days apart around a retrograde turn, are the dates the unknown hour could move most.

Questions about Mukesh Ambani’s birth chart

What is Mukesh Ambani's zodiac sign?

Aries. The Sun stayed in Aries all day on April 19, 1957, so the sign holds whatever the birth hour.

What is Mukesh Ambani's Moon sign?

Sagittarius or Capricorn: in the tropical zodiac the hour decides, Sagittarius until 12:07 PM Aden time and Capricorn afterward. In the Lahiri sidereal zodiac the Moon stayed in Sagittarius all day.

Is Mukesh Ambani's birth time known?

No. No record, biography or statement by Ambani giving an hour turned up, and AstroSage's 7:53 PM rests on an astrology book not seen here.

Which rising signs remain possible in Mukesh Ambani's chart?

Every one of them. Each sign held Aden's eastern horizon for between 1 hour 40 minutes and 2 hours 11 minutes that day. The AstroSage time would give Scorpio, but the page adopts no unbacked hour.

What ranks first in Mukesh Ambani's chart?

Combust Venus, never more than 1°22′ from the Sun that day; combust Venus turns up in about one chart in 8 born in the 1950s. Its move from Aries into Taurus at 6:28 AM leaves its sign, not its combustion, to the hour.

Which databank chart is nearest to Mukesh Ambani's?

Emma Watson's ranks closest, then Rodrigo Duterte's, B. R. Ambedkar's and Heath Ledger's, each sharing only the Aries Sun.

Two Aden midnights and a simulated sample

Planets were placed with precise astronomical calculations at the two Aden midnights bounding the date, and aspects sampled every 10 minutes of the local date. Rates count each feature among simulated 1950s births at random hours, in cities drawn by the square root of their population, run through the same detection code as this page.
