Wikidata records 7 members of Billlie. 7 of them have a birth date on record, born between 1999 and 2006. The ages below are as of 2026 — the birth dates are not.
7 people are on record, the usual size for a Korean group page here. Every one of them has a birth date, so nothing in the age table is estimated. The birth years run 1999–2006 — 7 years between the oldest and youngest recorded. 3 of them share the same star sign (Aquarius). Wikidata gives a birthplace for 2 of them, across 2 different places.
Ages are as of 2026; birth dates do not move. These are the members Wikidata records, not the current line-up — people who have since left are included and we cannot tell the two apart.
Moon Sua, born 9 September 1999 — 27 in 2026. The youngest is Haruna, born 30 January 2006, 20 in 2026. That is a gap of 7 years.

A dash means we hold no figure, not a zero.
The sign column is arithmetic on a birth date and nothing else. We do not say what any of it means, because we have not measured anything that would let us say it.
We did test the nearest thing to a claim. Across 1,047 Korean actors who reached a Netflix chart, the spread across birth-year animals was indistinguishable from chance. That test is here, with the working shown. Sign boundaries also move by a few hours from year to year, so someone born on a boundary day may fall the other way in their own birth year.
Wikipedia language count is not a measure of how good someone is. It measures how widely they are written about, and it favours people who have been famous longer.
We do not publish heights. Wikidata records a height for about 3% of the Korean performers we hold, and a figure built on 3% would be wrong far more often than right.
We hold 428 Korean groups in all. 165 of them have fewer than 3 members we could name, and we do not publish a page for those — they are counted, not hidden.
Wikidata records 7. This is not the current line-up — the field holds everyone recorded as part of the group, including people who have left.
They were born between 1999 and 2006. The full list of dates is in the table above. Birth dates do not move; ages do — the ages here are as of 2026.
We cannot tell you. Wikidata records a height for about 3% of the Korean performers we hold. We would rather say we do not know than publish a figure that would be wrong far more often than right.
