About EDT to JST Conversion

Converting time between EST and JST requires understanding their time zone offsets and any daylight saving time adjustments. EST (EDT) operates at UTC-5, while JST (JST) is set to UTC+9. This means JST is 14 hours ahead EST. Note that due to the time difference, the date may change. When it's 11:55 PM EDT on January 13, 2026, it's 1:55 PM JST on January 14, 2026 in JST. America/New_York observes daylight saving time, switching between EST (UTC-5) and EDT (UTC-4), while Asia/Tokyo does not observe daylight saving time. Use this converter to quickly find the equivalent time in JST for any time in EST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
