GMT to SGT Time Converter

GMT means Greenwich Mean Time (UTC+0); SGT means Singapore Standard Time (UTC+8). These named offsets do not change with the season. The city planner below follows local clock changes instead.

GMT means UTC+0 year-round. London uses GMT in winter. When the UK observes summer time the abbreviation becomes BST (British Summer Time, UTC+1). GMT and UTC share the same offset (UTC+0) but are technically distinct standards. The city planner uses Europe/London.

  • 9:00 AM GMT = 5:00 PM SGT
  • 12:00 PM GMT = 8:00 PM SGT
  • 5:00 PM GMT = 1:00 AM SGT (next day)

Local-time planner: London and Singapore. Cities follow their own DST rules. The reference sections below use October 13, 2026 in London; changing the planner does not update those sections.
