Korean Public Holidays: When to Book (and Avoid) a Clinic Trip
If your Korea trip includes clinic appointments, avoid Seollal and Chuseok, when nearly all skin clinics close for several days, and expect clinics to be heavily booked by locals on long holiday weekends. Late April and November are the easiest months to book. Holiday dates follow the lunar calendar and change every year, so confirm them and ask each clinic for its closed days before you fly.
The dated calendar below covers a single year. Korean public holidays shift against the lunar calendar, so check the current year's dates before booking anything around them.
The "Do Not Book" Dates: Seollal and Chuseok
If you are traveling to Korea primarily for dermatology treatments, there are two major holidays you must avoid at all costs: Seollal (Lunar New Year) and Chuseok (Korean Thanksgiving). These are Korea’s most significant traditional family holidays, and almost the entire country shuts down. Nearly all premium skin clinics in Gangnam and Myeongdong will completely close their doors to allow their doctors and staff to visit their hometowns. The official Seollal holiday runs from Monday, February 16 to Wednesday, February 18. Similarly, the Chuseok holiday falls in the autumn, specifically from Thursday, September 24 to Saturday, September 26. Arriving during these windows means you will be met with locked clinic doors, regardless of how badly you want that glass skin treatment.
New Golden Weekends in the Calendar
Even if you avoid the two major holidays, Korea has a robust substitute holiday system that creates long "golden weekends." A crucial, brand-new update for 2026 travelers: Constitution Day (July 17) has officially been reinstated as a public holiday after 18 years. Because July 17 falls on a Friday, it automatically creates a massive three-day weekend right at the start of the summer peak season. Add this to other substitute holidays—like Independence Movement Day (March 1) and Liberation Day (August 15) pushing to Mondays—and you get periods where clinics are overwhelmingly packed with local Koreans using their days off for laser treatments. Booking an appointment during these long weekends is incredibly difficult, and wait times inside the clinics can be much longer.

Best Months to Book, and What Timing Cannot Fix
With July now featuring a major long weekend, when is the easiest time to book? Looking at the calendar alone, late April and November are the clearest windows. April sits after Seollal and before the string of May holidays such as Children's Day, and November falls after the Chuseok travel rush and before the busy Christmas and New Year period. Fewer holidays mean fewer locals competing for the same appointment slots, and mild weather makes getting between clinic, hotel and pharmacy by public transport easier.
Good timing has limits, though. It cannot make a treatment suitable for your skin; only an in-person consultation can decide that, and a good clinic may suggest a gentler option or none at all. It does not shorten downtime, which depends on the procedure and on your skin, not on the season. Some treatments are planned as a course of sessions weeks apart, which one short trip cannot complete. And whatever the month, follow the clinic's own aftercare instructions on sun and heat rather than relying on cooler weather to protect healing skin.
How to Confirm Clinic Hours Before Flying
Never assume a clinic is open just because Google Maps says so. Korean businesses strictly follow the national red-day calendar (red days are official public holidays). Before booking your flight, the smartest move is to check the clinic's official Instagram page. Korean clinics actively post their holiday schedules under the Korean word "휴진" (Hyujin), which means "closed for medical treatment." Alternatively, reach out to their English-speaking concierges via WhatsApp, LINE, or KakaoTalk at least a month in advance. Confirm your exact treatment date and ensure that the specific head doctor you want is not taking personal leave during your targeted week.
Dr. Beau's Note
The calendar matters less for the appointment itself than for the days after it. If a treatment lands right before a three-day holiday, the clinic that performed it may be closed exactly when a question comes up, and most early concerns, such as unexpected swelling or a reaction to a prescribed cream, are easier to handle when you can call the same team. So plan backwards: check the holiday dates first, then book so the clinic stays open for several days after your visit.
Before you pay, ask how the clinic handles questions during a closure and save the answer on your phone. If something feels seriously wrong and the clinic is shut, do not wait for it to reopen: Korea's emergency number, 119, works on holidays too.
