NoCapWiki editorial explanation
1. What does it mean?
캘박 combines a shortened 캘린더 with 박기, a playful way to talk about fixing something in place. In a planning chat, '캘박했어' means 'I've put it in my calendar.' It is an informal action word for remembering an appointment, release date or other planned event, not the name of a calendar app.
Also written or said as 캘린더에 박기, 캘박하다, save the date, kaelbak
2. The nuance
'다들 캘박해' is a friendly reminder to save the date. It does not prove that everyone has confirmed attendance, purchased a ticket or received a formal invitation. Compare 칼답, replying quickly: a fast reply and a saved date are separate steps. If arrangements are tentative, say so before asking people to 캘박. In a work message, '일정에 등록해 두겠습니다' conveys the same practical action with a more professional tone. The shortened form fits friends' group chats better than a formal meeting invitation.
3. Examples
“장소는 아직 미정이지만 날짜는 캘박해 뒀어.”
The venue isn't decided yet, but I've saved the date in my calendar.
“캘박했다고 참석 확정이라는 뜻은 아니야.”
Putting it in my calendar doesn't mean I've confirmed that I can attend.
