Numbers in K-pop talk

Anniversaries use Sino-Korean numbers, so 1주년 is read 일주년 (iljunyeon). 주년 (junyeon) counts the years since a milestone. That makes 데뷔 5주년 (debwi ojunyeon) the fifth debut anniversary and 10주년 (sipjunyeon) the tenth. Fans celebrate these dates with events, hashtags and special content.

1위 is written 일위 but pronounced smoothly as [이뤼], romanized irwi, because the final ㄹ links into the next syllable. 위 (wi) is the counter for rankings, so 2위 is iwi and 3위 is samwi. Fans' happiest message after a music show win is 1위 축하해 (irwi chukahae), 'congrats on first place!'

100일 is read 백일 (baegil). Korea has a tradition of marking 100-day milestones, such as a baby's 백일, so fans celebrate a group's 100th day since debut too. A 1,000-day milestone is 천일 (cheonil). Both use Sino-Korean numbers followed by 일 (il, day).

3관왕 (samgwanwang) means winning three titles or first-place trophies, a 'triple crown.' When a song wins first place on music shows three times, fans say 3관왕 달성 (samgwanwang dalseong), 'achieved a triple crown.' The number is Sino-Korean, so it continues as 오관왕 (ogwanwang, five) and 십관왕 (sipgwanwang, ten).

Album numbers use Sino-Korean numbers: 1집 is 일집 (iljip) and 2집 is 이집 (ijip). 집 (jip) counts albums in order. So 정규 1집 (jeonggyu iljip) is a group's first full-length album and 미니 2집 (mini ijip) is their second mini album, a phrase you will see on almost every album page.

기 (gi) marks a group's 'generation' or intake. A fan club's 1기 (ilgi) is the first batch of members recruited, and 2기 (igi) is the second. The same word counts supporter groups, trainees or school graduating classes, always with Sino-Korean numbers.

년 차 (nyeon cha) means 'in the Nth year,' so 데뷔 7년 차 means a group is in its seventh year since debut. It is read with Sino-Korean numbers, 칠년 차 (chillyeon cha). Office workers use the same pattern, as in 3년 차 직장인 (samnyeon cha jikjangin), 'a worker in their third year.'

Korean groups large numbers by four digits, using 만 (man, 10,000) and 억 (eok, 100,000,000). So 100 million views is 1억 뷰 (ireok byu), and 10 million is 천만 (cheonman). These units do not line up with English million and billion, so it takes practice to convert quickly.

조회수 (johoesu) means view count, the number of times a video or post has been watched. When a music video drops, fans rally with 조회수 올리자 (johoesu ollija), 'let's raise the views.' 조회수 천만 돌파 (johoesu cheonman dolpa) means it has passed 10 million views.

Use native Korean numbers with the counter 명 (myeong): 일곱 명 (ilgop myeong) for seven, 다섯 명 (daseot myeong) for five. Watch out for one to four, which change form before a counter: 한 명 (han myeong), 두 명 (du myeong), 세 명 (se myeong), 네 명 (ne myeong).

Ordinals use native numbers plus 번째 (beonjjae). The exception is 'first,' which is 첫 번째 (cheot beonjjae), not 한 번째. After that it is regular: 두 번째 콘서트 (du beonjjae konseoteu, second concert) and 세 번째 앨범 (se beonjjae aelbeom, third album).

Months are Sino-Korean numbers plus 월 (wol), but two are irregular: June is 유월 (yuwol), not 육월, and October is 시월 (siwol), not 십월. The rest follow the rule, like 삼월 (samwol, March) and 구월 (guwol, September). Learners often slip on these when giving an idol's birthday.

Koreans long used counting age in daily life, where you are one at birth, but laws and official documents use international age, called 만 나이 (man nai). Since June 2023, a law has made international age the standard. Among fans, people also often just mention someone's birth year.

Birth years take 년생 (nyeonsaeng). Born in 2000 is 이천년생 (icheonnyeonsaeng), and the short form 00년생 is commonly read 공공년생 (gonggong nyeonsaeng), using 공 (gong) for zero. For 99년생, read the digits one by one: 구구년생 (gugu nyeonsaeng). Fans use this to talk about members' ages.

Hours use native numbers and minutes use Sino-Korean numbers. So 오후 6시 is 오후 여섯 시 (ohu yeoseot si, 6 p.m.), and 6:30 is 여섯 시 삼십 분 (yeoseot si samsip bun). 정각 (jeonggak) means 'on the dot,' handy when a release goes live exactly on the hour.

하나 (hana), 둘 (dul), 셋 (set) are native numbers used to count down before a photo or a group greeting. Idols often say 하나, 둘, 셋! before shouting their group's greeting together. When taking photos, people may add 김치! (gimchi) at the end, much like saying 'cheese.'

첫콘 (cheotkon) is the first concert of a tour or run of shows, and 막콘 (makkon) is the last one. Each show in a multi-day run is a 회차 (hoecha), as in 2회차 공연 (ihoecha gongyeon), the second show. These are fan abbreviations, common on social media during tours.

In math or scores, zero is 영 (yeong), but when reading digits one by one, like phone numbers or codes, Koreans usually say 공 (gong). So 010 is read 공일공 (gongilgong). A score of 1 to 0 is 일 대 영 (il dae yeong). Both are correct depending on the context.

1004 is read 천사 (cheonsa), which also means 'angel,' so it stands for angel. 8282 is read 팔이팔이, which sounds like 빨리빨리 (ppalli ppalli, 'hurry, hurry'). Fans slip these into cheering messages or nicknames. They are playful, so keep them out of formal writing.

Fans often shorten birthdays and anniversaries to four digits in month-month-day-day order, so 1115 means November 15. When a year is included, Korea writes dates year-month-day, as in 2026.11.15. Knowing this order helps you avoid mixing up dates written in other formats.
