23 Korean stars born on 11 April — 4 K-pop idols

Is that rank meaningful? Inside what an even scattering produces on its own. The rank is real, but the gap that made it is not: a day or two either way would move it a long way.

1 January is not a real peak. It is the date records fall back on when only a birth year is known, so this count includes people whose real birthday is unknown. We leave it in the table rather than quietly dropping it, but it should not be compared with the other 365 days.

We scattered the same number of birthdays evenly across 366 days 400 times, with a fixed seed (20260904) so the figure can be reproduced. On that footing a single day lands between 17 and 34 people 90% of the time. A count inside that band tells you about the calendar, not about the day.

This is a count, not a verdict. A crowded birthday does not make anyone more likely to become a star, and a thin one does not make anyone less likely. We hold birth dates only for people who already have a Wikidata entry — who reaches an encyclopaedia at all is its own filter, and we did not measure it.

Sharing a birthday means sharing a birthday. Nothing on this page says it means anything else. We counted whether a birth year predicts who reaches a chart, and it does not — that test is here.

This is not a horoscope. We do not read birth charts and we do not say what a date means about a person. Birth dates come from Wikidata; how widely each name is read is counted from English Wikipedia.
