WET to JST Converter

Converting Western European Time to Japan Standard Time

Western European Time (WET) and Japan Standard Time (JST) are separated by a 9 hours time difference. JST is 9 hours ahead of WET. WET is UTC+0, used in Portugal, United Kingdom, Ireland, while JST is UTC+9, used in Japan.

When converting from WET to JST, the key reference points to remember are: 9:00 AM WET equals 6:00 PM JST, 12:00 PM noon WET equals 9:00 PM JST, and 5:00 PM WET equals 2:00 AM JST. The conversion table above shows every hour of the day mapped between these two time zones.

Scheduling Across WET and JST

For professionals scheduling meetings between WET 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 9 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

WET observes Daylight Saving Time, switching to WEST (UTC+1) 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.
