About these time zones
Eastern Standard Time (EST)
Eastern Standard Time (EST) is UTC-5. Most places on Eastern Time use EST only in winter; from the second Sunday in March to the first Sunday in November they observe Eastern Daylight Time (EDT, UTC-4). People often write “EST” all year when they mean Eastern Time, so check which one is in effect.
Japan Standard Time (JST)
Japan Standard Time (JST) is UTC+9 all year across the whole of Japan. Japan has not observed daylight saving time since 1951. JST shares its offset with Korea Standard Time.
