What GMT and CST mean here

GMT (Greenwich Mean Time) is UTC+0 and never changes. The UK only uses GMT in winter: from March 29 to October 25, 2026 London is on BST (British Summer Time, UTC+1). If you want the actual time in the UK, use a London page instead; this page converts strict GMT.

Here CST means US Central Time: Chicago, Dallas, Houston, Minneapolis, New Orleans and Winnipeg. That's CST (UTC−6) in winter and CDT (UTC−5) from March 8 to November 1, 2026. CST is also the abbreviation for China Standard Time (UTC+8) and Cuba Standard Time; for China, search for Beijing or "China Standard Time" in the converter.
