Korean public holidays are more than just calendar dates—they’re critical markers that shape how business is conducted across South Korea. Unlike countries with fixed, predictable holidays, Korea’s schedule includes a blend of fixed-date, lunar-based, and substitute holidays, many of which change annually. For foreign entrepreneurs, investors, or global teams operating in Korea, understanding when the country effectively pauses is essential to avoid missteps—from delayed shipments to unresponsive partners during key business periods.
In addition to official Korea national holidays, there are culturally significant days such as Labor Day (May 1st)—not a legal public holiday but widely observed by private sector employers—that can also affect staffing and operations. In this guide, we’ll explain how the public holiday system in South Korea works, including the rules for substitute holidays and lunar-based shifts, and provide actionable insights on how to align your business calendar with local norms.
1. Overview of Korean Public Holidays
As of 2025, South Korea designates 15 public holidays under the “Regulations on Holidays of Government Offices”, which legally apply to public sector offices and serve as a de facto standard for many private businesses. These holidays include internationally recognized days such as New Year’s Day (January 1) and Christmas (December 25), as well as culturally specific observances like Seollal (Lunar New Year) and Chuseok (Korean Thanksgiving), which follow the lunar calendar and typically include three consecutive days of nationwide closures.
It is important to distinguish between official holidays and customary non-working days. For example, May 1st (Labor Day) is not a legal public holiday under the above regulation but is treated as a paid holiday under Article 55 of the Labor Standards Act, particularly in workplaces with five or more employees. Likewise, substitute holidays (대체공휴일) are legally mandated when major holidays like Seollal, Chuseok, or Children’s Day fall on weekends—ensuring continuity of rest days.
Foreign employers should note that while government offices and banks close on public holidays, small businesses and foreign-invested firms may operate based on their own policies. Therefore, proper holiday scheduling requires both legal awareness and local practice alignment.
2. Substitute Holidays: What You Need to Know
To ensure consistency in national rest periods, South Korea operates a substitute holiday system (대체공휴일 제도) for certain public holidays that fall on weekends. When a major holiday such as Seollal (Lunar New Year) or Chuseok (Korean Thanksgiving) overlaps with a Saturday or Sunday, an alternative weekday—typically the following Monday—is designated as a day off.
As of recent policy expansions, this system also covers Children’s Day (May 5), National Liberation Day (August 15), and Hangul Day (October 9). Since these substitutions vary depending on the calendar year, it is essential for businesses to review the official government holiday schedule annually.
For foreign companies operating in Korea, overlooking substitute holidays can lead to unexpected disruptions in operations, including delays in shipments, halted campaigns, or missed meetings. A common pitfall is assuming that multi-day holidays follow the same weekday cycle every year—when, in fact, the substitution may shift closures to a different period within the business week.
3. Lunar Holidays and Annual Variations
Some of South Korea’s most significant national holidays—such as Seollal (Lunar New Year) and Chuseok (Korean Thanksgiving)—are based on the lunar calendar, meaning their dates shift annually on the Gregorian calendar. Seollal typically falls between late January and mid-February, while Chuseok usually occurs between late September and early October. Both holidays span three consecutive days: the day before, the main holiday, and the day after—resulting in widespread closures across government offices, banks, and most businesses.
In addition to these, Buddha’s Day (부처님오신날), which also follows the lunar calendar, generally falls in April or May. Though its religious nature may not affect all industries equally, it is still a legally designated public holiday and widely observed.
These periods are also peak seasons for domestic travel and family gatherings, with many employees requesting additional days off. Consequently, foreign-invested companies must factor in these annual variations when planning operations, employee leave, or regulatory filings.
Moreover, election days—including presidential, parliamentary, or local elections—are often declared temporary public holidays (임시공휴일). For example, June 3, 2025, was designated a public holiday due to the presidential election. These can disrupt regular operations, and their announcement may occur with short notice.
To avoid scheduling conflicts or compliance delays, it is advisable to consult the official annual holiday calendar published by the Ministry of Personnel Management (인사혁신처) or work with a local secretarial service in Korea. This is particularly important when preparing for HR deadlines, tax filings, and corporate registration procedures that may fall within or near holiday periods.
4. How to Plan Around Korean Holidays
When managing operations in South Korea, it’s essential to plan not only for the official public holidays but also for the days surrounding major events like Seollal and Chuseok. These multi-day holidays—based on the Korean lunar calendar—typically result in a nationwide pause across government offices, banks, customs, and logistics providers. Even before or after the official dates, delays in processing and reduced staffing levels are common.
For foreign companies and investors, understanding the Korean public holiday schedule helps avoid unnecessary disruptions. Service-based firms may notice decreased responsiveness from clients and employees during these periods, making them more suitable for internal reviews, planning sessions, or non-client-facing activities.
Incorporating public holidays in South Korea into your business calendar not only improves operational efficiency but also demonstrates cultural awareness—an increasingly important factor in maintaining strong relationships with Korean stakeholders.
