This GMT to SGT converter turns any time in Greenwich Mean Time (GMT) into Singapore Time (SGT), using your device clock so daylight saving is applied automatically. SGT is 8 hours ahead of GMT. GMT is UTC+0; SGT is UTC+8.
GMT covers Accra, Dakar, London in winter; SGT covers Singapore, Kuala Lumpur (MYT), Manila (PHT). 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 GMT and SGT?
SGT is 8 hours ahead of GMT. That comes from the UTC offsets: GMT is UTC+0 and SGT is UTC+8. For example, 9 am GMT = 5 pm SGT.
Is SGT ahead of or behind GMT?
SGT is 8 hours ahead of GMT, so when it is noon in GMT it is 8 pm in SGT. Ahead means the clock there already shows a later time; a call at 5 pm GMT lands at 1 am SGT.
Does GMT or SGT observe daylight saving time in 2026?
No. Neither GMT nor SGT changes its clocks, so the 8 hours difference holds every day of the year. That makes recurring meetings between Accra and Singapore easy to keep at a fixed local time on both ends.
What is the best time for a meeting between GMT and SGT?
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 GMT = 4 pm SGT and 6 pm GMT = 2 am SGT the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use GMT and SGT?
GMT (Greenwich Mean Time) is used in Accra, Dakar, London in winter. SGT (Singapore Time) is used in Singapore, Kuala Lumpur (MYT), Manila (PHT). 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.
