What JST and EST mean here

JST (Japan Standard Time) is UTC+9 all year; Japan doesn't use daylight saving time. Tokyo and Osaka are on the same clock. Korea (KST) has the same offset, so the result is also right for Seoul.

EST (Eastern Standard Time, UTC−5) is the winter time in New York, Washington, Atlanta, Miami and Toronto. From March 8 to November 1, 2026 those places use EDT (Eastern Daylight Time, UTC−4) instead. Most people who write "EST" mean "Eastern Time, whatever the clocks say today", so this converter follows the clocks in New York and switches between EST and EDT on the right days.
