A public-holiday calendar records the days Korea has set aside as statutory time off. National holidays apply nationwide; where an official regional or provincial list is published, those dates are included separately and clearly labelled rather than folded into the national figures. This calendar is a reference, not a legal determination of anyone's leave entitlement. Dates move for two common reasons: many countries observe a fixed-date holiday on the nearest working day when it falls at a weekend, and some observances follow lunar or other non-Gregorian reckoning that shifts against the everyday calendar. Regional holidays are always shown as regional and never added to the national count. The licence terms and the government producer behind each list are credited on the sources page.
Reading the table
The table gives the date a holiday falls on, the observance date when a weekend shift or substitute day applies, and notes published with the source. A Regional · <region> badge marks a holiday that applies only in that region; it is never counted as nationwide. Some countries publish both the original date and the observed date, so both are shown instead of silently adjusting one. Employers, schools, and individual workplaces may follow different calendars or grant extra days, so treat this table as a guide rather than an entitlement. For a wider comparison of why observance moves between countries, see why holiday dates differ between countries. The official source is always the final authority.
Where these dates come from
Korea's statutory holidays are taken from the Ministry of the Interior and Safety and reused under the Korea Open Government Licence Type 1. The dates follow the Regulations on Public Holidays, which set the national list; the three-day Seollal and Chuseok clusters and Children's Day are all covered. Korea applies substitute holidays: when a holiday falls at a weekend or overlaps another holiday, the next non-holiday day can be designated as an alternative holiday, and the desk shows the observed date with the actual one noted. Lunar dates such as Seollal, Buddha's Birthday and Chuseok move each year against the Gregorian calendar, so they cannot be computed from a fixed rule. Korea has no provincial public holidays, so every listed date is nationwide. The ministry updates the list when the regulations change; this desk is rebuilt from it. Some years also see temporary holidays for elections or national events. The three-day clusters mean a single observance contributes several rows to the table rather than one.
