Why Choose Our JST to EST Converter
With 14 hours between JST and EST, business-hours overlap is limited. This tool instantly shows which hours work on both sides, so you can lock in a meeting without a chain of "does 3 PM work for you?" emails.
A JST evening at 9 PM is already the previous afternoon in EST. This converter flags date changes beside the result — critical when booking flights, hitting deadlines, or scheduling across the Japan–United States corridor.
Daylight Saving adjustments can widen or narrow the JST–EST gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in JST. Convert the event time to EST so you know exactly when to tune in — with a 14 hours difference, a morning event in Japan hits the evening in United States.

JST to EST Time Difference, Business Hours, and DST
JST to EST is one of the more useful timezone conversions for calls, deadlines, and travel planning. The current gap is 14 hours, which means 9:00 AM JST becomes 7:00 PM (previous day) EST and 2:00 PM JST becomes 12:00 AM EST.
This matters when teams in Tokyo and New York need to align business hours, webinars, or customer-support coverage. Use the chart on this page when you want the exact conversion for today instead of relying on manual offset math.
Daylight saving changes can also shift the gap during the year, so a converter is safer than memorizing a fixed difference. That is especially important for recurring meetings and date-sensitive handoffs.
