Converting Eastern Standard Time to Japan Standard Time
Eastern Standard Time (EST) and Japan Standard Time (JST) are separated by a 14 hours time difference. JST is 14 hours ahead of EST. EST is UTC-5, used in United States, Canada, Jamaica, while JST is UTC+9, used in Japan.
When converting from EST to JST, the key reference points to remember are: 9:00 AM EST equals 11:00 PM JST, 12:00 PM noon EST equals 2:00 AM JST, and 5:00 PM EST equals 7:00 AM JST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across EST and JST
For professionals scheduling meetings between EST 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 14 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
EST observes Daylight Saving Time, switching to EDT (UTC-4) 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.
