This SGT to GMT converter turns any time in Singapore Time (SGT) into Greenwich Mean Time (GMT), using your device clock so daylight saving is applied automatically. GMT is 8 hours behind SGT. SGT is UTC+8; GMT is UTC+0.
SGT covers Singapore, Kuala Lumpur (MYT), Manila (PHT); GMT covers Accra, Dakar, London in winter. Neither zone observes daylight saving time, so the difference is the same every day of the year.

Frequently asked questions
What is the time difference between SGT and GMT?
GMT is 8 hours behind SGT. That comes from the UTC offsets: SGT is UTC+8 and GMT is UTC+0. For example, 9 am SGT = 1 am GMT.
Is GMT ahead of or behind SGT?
GMT is 8 hours behind SGT, so when it is noon in SGT it is 4 am in GMT. Ahead means the clock there already shows a later time; a call at 5 pm SGT lands at 9 am GMT.
Does SGT or GMT observe daylight saving time in 2026?
No. Neither SGT nor GMT changes its clocks, so the 8 hours difference holds every day of the year. That makes recurring meetings between Singapore and Accra easy to keep at a fixed local time on both ends.
What is the best time for a meeting between SGT and GMT?
Office hours (9 am to 5 pm) do not overlap at all with a 8 hours difference. The least painful options are early morning in GMT or early evening in SGT; for example 8 am SGT = 12 am GMT and 6 pm SGT = 10 am GMT. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use SGT and GMT?
SGT (Singapore Time) is used in Singapore, Kuala Lumpur (MYT), Manila (PHT). GMT (Greenwich Mean Time) is used in Accra, Dakar, London in winter. Note that the United Kingdom is only on GMT in winter; from late March to late October London runs on British Summer Time, one hour ahead, so use the BST pages for UK business hours in summer.
