About these time zones
British Summer Time (BST)
British Summer Time (BST) is UTC+1, used in the United Kingdom from the last Sunday in March to the last Sunday in October. The rest of the year the UK is on Greenwich Mean Time (GMT, UTC+0). Ireland switches on the same dates to Irish Standard Time.
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.
