About these two clocks

BST — UK time (British Summer Time). Used in London, Manchester, Edinburgh. BST is the UK summer clock (UTC+1). In winter UK clocks fall back to GMT; this page follows London clocks for the date you choose.

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 Europe/London and America/New_York explicitly.
