The 2026 Chuseok holiday period begins on Thursday, September 24. Chuseok day itself falls on Friday, September 25, and the statutory holiday runs for three days from Thursday the 24th to Saturday the 26th. With Sunday the 27th following, the actual days off total just four.

■ Why It Was Cut Short to Four Days

The last day of the holiday overlaps with Saturday, meaning one day was effectively absorbed into the weekend. Under government regulations on public holidays, substitute holidays for the Seol and Chuseok holidays are granted only when they overlap with a Sunday or another public holiday; overlap with a Saturday is not covered. This differs from national holidays such as National Foundation Day (Gaecheonjeol) and Hangul Day, which receive substitute holidays even when they fall on a Saturday.

■ September 28 Temporary Holiday Effectively Off the Table

There had been anticipation that Monday the 28th, immediately after the holiday period, would be designated a temporary public holiday. Temporary holidays are designated by the government through a Cabinet Council resolution. However, as of the time of writing on the 23rd, the day before the holiday, no government designation announcement or Cabinet Council resolution had been confirmed. The mood is that it is effectively off the table.

September 28 is a regular working day. However, taking annual leave that day allows five consecutive days off from the 24th through the 28th.

■ The October Calendar Is the Remedy... Three-Day National Foundation Day Holiday

The disappointment of a short Chuseok could be made up for in the October calendar a week later. Because National Foundation Day on October 3 falls on a Saturday, the following weekday, Monday the 5th, becomes a substitute holiday. As a result, a three-day holiday runs from the 3rd through the 5th.

The October holiday feels even bigger because of what follows on the calendar. There are no public holidays at all in November 2026. After October 11, the next public holiday is Christmas on December 25, meaning more than roughly 10 weeks of only weekdays in a row. Christmas falls on a Friday, creating a three-day holiday from the 25th through the 27th.

■ Checking Annual Leave Calculations in Advance Is Key

There is consolation to be found in resting more later to make up for the shortened Chuseok break. If you carefully check the dates ahead of National Foundation Day, you may be granted a significant holiday opportunity. How you use your time will be key in October as well.
