Korea stock market calendar: May 2026

IPO subscriptions and refunds, bonus-issue ex-rights and listing dates, option expiry and KRX holidays in one calendar.

← AprJun →

Dates are Korea Standard Time (UTC+9), which does not shift for daylight saving. The Korea Exchange trades 09:00–15:30 KST and closes completely on public holidays — the Lunar New Year and Chuseok holidays move each year and can shut the market for several days in a row. IPO dates, ex-rights dates and lock-up expiries come from the filings companies publish on DART, so they appear here as soon as the filing does. You can subscribe to this calendar from the alerts page.

The ex-rights date is the trading day before the record date (T+2 settlement), so buy by the day before the ex-rights date to receive new shares. Monthly options expire on the second Thursday (earlier if it is a holiday). Confirm all dates with company filings and Korea Exchange notices.
