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.
