JST to CET Converter – Convert Japan Time to Central European Time

CET is 8 hours behind JST, so to convert mentally, subtract 8 hours to your JST time. For example: 9:00 AM JST = 1:00 AM CET. Our converter automatically adjusts for Daylight Saving Time so you always get the right result.

CET (Central European Time, UTC+1) is 8 hours behind JST (Japan Standard Time, UTC+9) during standard time. For example, 9:00 AM JST = 1:00 AM CET. During DST periods, this difference changes by 1 hour when one or both zones observe Daylight Saving Time — our converter automatically applies the correct offset for any date you select.

JST is 8 hours behind CET, so standard 9–5 business hours do not overlap. The most practical window is late afternoon in JST (5–7 PM), which falls in the morning in CET — for example, 5:00 PM JST = 9:00 AM CET. Use our meeting planner to find the exact time for your date, especially around DST transitions.

Japan does not observe Daylight Saving Time. JST remains constant year-round, which simplifies conversions.

Major cities in the JST (Japan Standard Time, UTC+9) timezone include: Tokyo, Osaka, Yokohama, Nagoya, Sapporo, Kyoto, Fukuoka. JST is a fixed-offset zone — these cities do not observe Daylight Saving Time.

Major cities in the CET (Central European Time, UTC+1) timezone include: Paris, Berlin, Rome, Madrid, Amsterdam, Vienna, Warsaw, Brussels. These cities switch to CEST (UTC+2) from the last Sunday in March to the last Sunday in October.

CET is 8 hours behind JST. Because JST and CET are 8 hours apart, there is no standard business-hour overlap — plan for one side to take an early morning or late evening call. Always include both local times in calendar invites (for example, "2:00 PM JST / 6:00 AM CET CET"). Double-check around March and November (or March/October for European zones) when DST transitions can shift the offset by 1 hour.
