What a substitute holiday is in Korea — why a Saturday Liberation Day means a Monday off
A substitute holiday in Korea moves a day off to the next non-holiday weekday when a public holiday falls on a Saturday, a Sunday or another public holiday. It does not apply to every public holiday — New Year's Day and Memorial Day are excluded. In 2026 Liberation Day fell on Saturday, August 15, which made Monday, August 17 a substitute holiday
The three lines
- Principle — when a public holiday collides with a weekend or another holiday, the next non-holiday weekday is taken instead
- Exceptions — New Year's Day and Memorial Day are excluded. Memorial Day is explained as a day of remembrance rather than a national celebration day
- In practice — Liberation Day 2026 fell on Saturday, August 15, so Monday, August 17 became a substitute holiday and the stock market closed with it
Key questions
- What is a substitute holiday?
- A rule that moves a day off to the next non-holiday weekday when a public holiday collides with a weekend or another public holiday. It rests on the Act on Public Holidays, its enforcement decree and the Regulation on Public Holidays for Government Offices. The purpose is simple: to make the statutory number of public holidays real. If a holiday lands on a Saturday it overlaps a day that was already free, and the day is effectively lost. The rule returns it by moving it to a weekday.
- Does it apply to every public holiday?
- No. It applies to the national celebration days — Independence Movement Day, Liberation Day, National Foundation Day and Hangeul Day — as well as the Lunar New Year and Chuseok holidays, Children's Day, Buddha's Birthday and Christmas. It does **not** apply to New Year's Day (January 1) or Memorial Day. The explanation offered for Memorial Day is its character: it is a statutory public holiday but not a national celebration day — it is a day of national remembrance rather than a day marking a national occasion. In 2026 Memorial Day, June 6, fell on a Saturday and no substitute holiday was created.
- Why do the collision rules differ by holiday?
- They fall into two groups. The Lunar New Year and Chuseok holidays qualify when they collide with a **Sunday or another public holiday** — those holidays already run three days, so the Saturday case is built into the count. Independence Movement Day, Liberation Day, National Foundation Day, Hangeul Day, Buddha's Birthday and Christmas qualify when they collide with a **Saturday or a Sunday**. Children's Day has the widest rule: Saturday, Sunday or another public holiday. That is why the same question comes up every year — 'it fell on a Saturday, so why is there no substitute?' The answer lies in the type of holiday, not the date.
Liberation Day 2026 fell on Saturday, August 15. The extra day off actually taken was Monday, August 17.
The mechanism that moves it is the substitute holiday.
1. The principle is one sentence
When a public holiday collides with a weekend or another public holiday, the next non-holiday weekday is taken instead.
The purpose is to make the statutory number of public holidays real. A holiday landing on a Saturday overlaps a day that was already free, and simply vanishes. The rule returns it as a weekday.
The legal basis is the Act on Public Holidays and its enforcement decree, together with the Regulation on Public Holidays for Government Offices.
2. What qualifies and what does not
| Category | Holiday | Substitute |
|---|---|---|
| National celebration days | Independence Movement Day · Liberation Day · National Foundation Day · Hangeul Day | applies |
| Traditional holidays | Lunar New Year · Chuseok | applies |
| Other | Children's Day | applies |
| Other | Buddha's Birthday · Christmas | applies |
| Other | New Year's Day (January 1) | excluded |
| Other | Memorial Day | excluded |
The last two rows produce the same argument every year.
3. Why Memorial Day is excluded
The reason offered is not about the date. It is about character.
| National celebration day | Memorial Day | |
|---|---|---|
| Character | a day marking a national occasion | a day of national remembrance |
| Examples | Independence Movement Day, Liberation Day, National Foundation Day, Hangeul Day | Memorial Day |
| Substitute holiday | applies | excluded |
Memorial Day is a statutory public holiday but not a national celebration day. National celebration days are defined in law as days marking an occasion of national significance, and Memorial Day is not of that kind — that is the stated basis for the exclusion.
Whether this matches the legislative intent, and whether it is a sufficient reason, is argued every year. In 2026 Memorial Day, June 6, did fall on a Saturday, and no substitute holiday was created.
4. The collision rule differs by holiday
| Holiday | Substitute arises when it collides with |
|---|---|
| Lunar New Year · Chuseok | Sunday or another public holiday |
| Independence Movement Day · Liberation Day · National Foundation Day · Hangeul Day | Saturday or Sunday |
| Buddha's Birthday · Christmas | Saturday or Sunday |
| Children's Day | Saturday, Sunday or another public holiday |
The Lunar New Year and Chuseok holidays omit Saturday because they already run three days, so that case is built into the count.
Children's Day has the widest rule — a substitute arises even when it collides with another public holiday.
This is why the same question recurs: "it was a Saturday too, so why is there no substitute?" The answer lies in the type of holiday, not the date.
5. Liberation Day 2026, worked through
| Date | Day | Status |
|---|---|---|
| August 15 | Sat | Liberation Day (public holiday) — collides with Saturday |
| August 16 | Sun | Sunday |
| August 17 | Mon | Substitute holiday |
Liberation Day is a national celebration day, so a Saturday collision produces a substitute. The following day, August 16, was a Sunday and therefore not a "non-holiday" weekday. The next available day was Monday, August 17, which produced a three-day weekend.
6. What closes and what does not
| Category | August 17 |
|---|---|
| Government offices | closed |
| Korean stock market | closed |
| Bank branches | closed |
| Internet and mobile banking, ATMs | normal |
| Emergency rooms | normal |
| Some clinics | individual decision |
The market closure has a real effect on investors, because it changes the basis of any weekly comparison.
This page covered that on the same day in "KOSPI weekly -0.93% (August 18–21)". The third week of August 2026 had four trading days, and the reference point for the weekly comparison was not August 17 but the August 14 close.
7. Common questions
Q. Is a substitute holiday paid? At a workplace where public holidays for government offices are guaranteed as holidays under the Labour Standards Act, yes. The scope varies with workplace size, and this page could not confirm the current thresholds.
Q. Is holiday pay owed for working on one? At a workplace where the day is a guaranteed holiday, working it counts as holiday work. The calculation follows the employment contract and work rules.
Q. Can two substitute holidays arise at once? Yes, if two public holidays fall consecutively against a weekend. The rule designates "the next non-holiday day", so multiple collisions push the designation outward.
Q. Why is New Year's Day excluded? It is not a national celebration day either. Unlike Memorial Day, however, this page could not find material setting out the reasoning separately.
8. What is not confirmed
- When Buddha's Birthday and Christmas were added — understood to be 2023, but the amendment's effective date was not checked against the primary text. Search results contain statements describing both the position before and after the expansion.
- The full 2026 calendar — not settled in this article. The two cases given are the ones confirmed by sources.
- Private-sector scope — the current thresholds by number of employees could not be confirmed.
- The reasoning for excluding New Year's Day — no separate explanatory material was found.
