On the 29th, the Korea AeroSpace Administration announced the "2027 Monthly Calendar Requirements," which serve as the standard for producing the 2027 calendar. The Monthly Calendar Requirements contain dates, seasonal divisions, public holidays, and commemorative days based on astronomical calendars, and are used as a standard for calendar production by both the government and the private sector.

Public Holiday Status

According to the Korea AeroSpace Administration, public holidays for government offices in 2027 total 76 days, including 52 Sundays, national holidays, substitute holidays, Labor Day, and Constitution Day. However, since Seollal (Lunar New Year), Memorial Day, Liberation Day, and National Foundation Day overlap with Sundays, the actual number of public holidays is 72 days.

For institutions operating on a five-day workweek, holidays total 124 days when including 52 Saturdays. However, excluding five public holidays that fall on Saturdays — the first day of the Seollal holiday, Labor Day, Constitution Day, Hangeul Day, and Christmas — the actual number of holidays is 119 days.

10 Long Weekends of 3 Days or More

In 2027, there will be a total of 10 extended holiday periods lasting three days or longer.
