About EST and UTC
Eastern Time (EST, UTC−5) covers New York, Toronto, Miami and Atlanta, and observes daylight saving (EST in winter, EDT in summer). Coordinated Universal Time (UTC, UTC+0) covers the global reference used in aviation, computing and science, and never changes for daylight saving.
Because Eastern Time observes daylight saving while the other side doesn't, the difference shifts by one hour between winter and summer — the table below shows both.
