The 2027 calendar has been confirmed. For government offices, there are a total of 72 public holidays, and "golden long weekends" lasting three or more days occur ten times a year. In particular, substitute holidays will be applied to Labor Day and Constitution Day — newly introduced starting in 2026 — for the first time, changing the holiday map.

How the 72 Days Add Up

According to the "2027 Calendar Summary" announced by the Korea AeroSpace Administration on June 29 via Official Gazette Notice No. 2026-0078, the total number of red-letter days on the calendar comes to 76, combining Sundays (52 days), national holidays, substitute holidays, and the newly introduced Labor Day and Constitution Day. However, since Lunar New Year (February 7), Memorial Day (June 6), Liberation Day (August 15), and National Foundation Day (October 3) fall on Sundays, subtracting four overlapping days brings the actual number of days off to 72.

119 Holidays for Five-Day Workers

For workplaces with a five-day workweek, adding Saturdays (52 days) brings the total to 124. However, after subtracting five public holidays that overlap with Saturdays (the first day of the Lunar New Year holiday on February 6, Labor Day on May 1, Constitution Day on July 17, Hangeul Day on October 9, and Christmas on December 25), the final total comes to 119 days.

Labor Day and Constitution Day Receive First Substitute Holiday Designation

The most notable change involves Labor Day and Constitution Day. Both holidays were newly incorporated as government office holidays in April 2026, and in 2027, they both happen to fall on Saturdays. Accordingly, substitute holidays have been designated for May 3 (Labor Day) and July 19 (Constitution Day), respectively.

Ten Golden Long Weekends: The Longest Is Four Days for Lunar New Year

Holiday periods of three or more days occur ten times throughout the year:

• January 1-3: New Year's holiday
• February 6-9: Lunar New Year holiday (four days) — the longest holiday stretch of 2027
• February 27-March 1: March First Independence Movement Day holiday
• May 1-3: Labor Day holiday
• July 17-19: Constitution Day holiday
• August 14-16: Liberation Day holiday
• September 14-16: Chuseok holiday
• October 2-4: National Foundation Day holiday
• October 9-11: Hangeul Day holiday
• December 25-27: Christmas holiday
