CET to JST Converter

Converting Central European Time to Japan Standard Time

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

When converting from CET to JST, the key reference points to remember are: 9:00 AM CET equals 5:00 PM JST, 12:00 PM noon CET equals 8:00 PM JST, and 5:00 PM CET equals 1:00 AM JST. The conversion table above shows every hour of the day mapped between these two time zones.

Scheduling Across CET and JST

For professionals scheduling meetings between CET and JST, 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

CET observes Daylight Saving Time, switching to CEST (UTC+2) during summer months. JST does not observe DST, staying at UTC+9 year-round. 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.
