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.
