Guide: Korea Standard Time (KST)
KST = UTC+9: Korea Standard Time is 9 hours ahead of Coordinated Universal Time (UTC). It is the same time zone as Japan Standard Time (JST). Korea uses a single time zone for the entire country.
No Daylight Saving Time: South Korea does not observe daylight saving time (DST). This means the time difference with countries that DO use DST (like the US and UK) changes twice a year. For example, New York is 14 hours behind Seoul in winter but 13 hours behind in summer.
Best times to call home: If calling the US East Coast from Korea, try 9-10 PM KST (8-9 AM EST). For the West Coast, 6-7 AM KST works well (2-3 PM PST previous day). For Europe, 5-6 PM KST is ideal (8-9 AM GMT).
Business hours in Korea: Standard Korean business hours are 9:00 AM to 6:00 PM, Monday through Friday. Banks typically open 9:00 AM to 4:00 PM. Government offices run 9:00 AM to 6:00 PM. Many restaurants stay open until 10:00 PM or later.
Date format: Korea uses the Year-Month-Day format (YYYY-MM-DD or YYYY.MM.DD). For example, July 4, 2026 is written as 2026-07-04 or 2026.07.04. This is different from the US format (MM/DD/YYYY) and the European format (DD/MM/YYYY).
24-hour vs 12-hour clock: Korea commonly uses the 12-hour clock in daily conversation with AM/PM markers (오전/오후). However, transportation schedules, military time, and formal contexts use the 24-hour format. Both are widely understood.
