V hasn't made a birth time public, and none of the times passed around online can be traced to a record. Known for certain: V was born on 30 December 1995 in Seo District, Daegu, South Korea. That gives a Capricorn Sun and an Aries Moon, with four more planets keeping the Sun company in Capricorn.
Two birth times for V turn up online, and neither has a source behind it. The earlier one, 5:56 AM, began as an anonymous question on Tumblr that cited “some korean fansite”, and the person asking added “Idk how true it is”. The later one, 8:00 PM, appears on an astrology site that doesn't say where it came from. Fans share these out of affection, which is lovely to see, but a time needs a source before it can be checked, so neither one is used here.
Five planets were in Capricorn on 30 December 1995: the Sun, Mercury, Mars, Uranus and Neptune. Capricorn is the sign of patience, craft and long-term goals, so with this many planets there the whole chart leans toward steady work and quiet mastery. Mars and Mercury both sit near Neptune, within about two degrees, which pours imagination into that discipline: effort guided by a dreamer's sense of beauty, and words with a poetic edge. Uranus, in the final degree of Capricorn, keeps things from ever turning ordinary.
Venus in Aquarius loves freely and warmly, with an eye for the unusual. Jupiter, late in Sagittarius, adds generosity and an appetite for adventure, and Saturn in Pisces lends the whole chart a gentle, compassionate patience.
The Moon was in Aries all day, from about 17° at midnight to 29° by the end of it. An Aries Moon is warm, spontaneous and brave with its feelings, a bright spark of play beside so much Capricorn calm.
A birth time would settle the rising sign and the houses, the two parts of a chart that depend on the clock. If the 5:56 AM time were right, it would put the rising sign in Sagittarius, at about 14°, and the Sun in the 1st house. The 8:00 PM time would put the rising sign in Leo instead, at about 12°, with the Midheaven in Taurus. Those answers have almost nothing in common, which shows how much rides on the exact hour. Until V shares it, both stay possibilities and nothing more.
