FAQ
Which years include holiday marks?
Korean public holidays for 2025–2027, including substitute holidays, are built in as static data. Other years still generate the calendar grid but without holiday marks, and election days or temporary holidays are never included.
How are substitute holidays determined?
Under the Korean public holiday regulations, a substitute holiday is added when the Seollal or Chuseok holiday run overlaps a Sunday, or when Independence Movement Day, Liberation Day, National Foundation Day, Hangeul Day, Children's Day, Buddha's Birthday, or Christmas falls on a Saturday or Sunday. Memorial Day and January 1 do not get substitutes.
Is calendar generator input sent to a server?
No. The calendar and the print view are generated entirely in your browser and nothing is sent to a server.
