JST to CET Converter

Converting Japan Standard Time to Central European Time

Japan Standard Time (JST) and Central European Time (CET) are separated by a 8 hours time difference. CET is 8 hours behind JST. JST is UTC+9, used in Japan, while CET is UTC+1, used in Germany, France, Italy.

When converting from JST to CET, the key reference points to remember are: 9:00 AM JST equals 1:00 AM CET, 12:00 PM noon JST equals 4:00 AM CET, and 5:00 PM JST equals 9:00 AM CET. The conversion table above shows every hour of the day mapped between these two time zones.

Scheduling Across JST and CET

For professionals scheduling meetings between JST and CET, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 8 hours difference, the window of overlap may be limited, making early morning or late evening calls necessary for one party. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.

Daylight Saving Time Considerations

JST does not observe Daylight Saving Time, maintaining UTC+9 year-round. CET observes DST, switching to CEST (UTC+2). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
