Public holidays in South Korea are commonly known as 'Red Days' as this is how they are usually coloured in printed calendars.
The Korean government has announced that from the second half of 2014 onwards, if the date of Seollal, Chuseok, or Children's Day falls on Sunday, then the holiday will be extended to Monday.
Since August 2021, March 1st Independence Movement Day, National Liberation Day, National Foundation Day and Hangeul Day have been added to the list of holidays that are compensated if they fall on a weekend.
Since March 2023, South Korean workers will enjoy an extra day off if either Buddha's Birthday or Christmas overlaps with a Saturday or Sunday.
