About these two clocks
JST — Japan Standard Time. Used in Tokyo, Osaka. Japan has no daylight saving time; it is UTC+9 all year.
EST — Eastern Time. Used in New York, Toronto, Miami, Atlanta. Strictly, EST is the winter name; from March to November the same clocks show EDT (UTC−4). This page follows the clocks, so summer dates use EDT.
All figures on this page come from the IANA time zone database (the same data your phone and laptop use), evaluated for the date in question. Abbreviations are ambiguous — “IST” also means Irish or Israel Standard Time, and “CST” is China Standard Time in Asia — so this page uses Asia/Tokyo and America/New_York explicitly.
