Converting Greenwich Mean Time to Singapore Time
Greenwich Mean Time (GMT) and Singapore Time (SGT) are separated by a 8 hours time difference. SGT is 8 hours ahead of GMT. GMT is UTC+0, used in United Kingdom, Ireland, Portugal, while SGT is UTC+8, used in Singapore.
When converting from GMT to SGT, the key reference points to remember are: 9:00 AM GMT equals 5:00 PM SGT, 12:00 PM noon GMT equals 8:00 PM SGT, and 5:00 PM GMT equals 1:00 AM SGT. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across GMT and SGT
For professionals scheduling meetings between GMT and SGT, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 8 hours difference, the window of overlap may be limited, making early morning or late evening calls necessary for one party. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
GMT observes Daylight Saving Time, switching to BST (UTC+1) during summer months. SGT does not observe DST, staying at UTC+8 year-round. During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
