About BST and EST

UK clocks show BST (British Summer Time, UTC+1) from the last Sunday in March to the last Sunday in October, and GMT (UTC+0) the rest of the year.

Eastern Time covers New York, Washington, Miami and Atlanta. It is EST (UTC−5) in winter and EDT (UTC−4) from the second Sunday in March to the first Sunday in November. People often write EST all year; this page follows the clocks.
