Frequently Asked Questions
What is the time difference between SGT and AEDT?
During standard time, Australian Eastern Daylight Time is 3 hours ahead of Singapore Time.
Does Singapore use Daylight Saving Time?
Singapore does not observe Daylight Saving Time and has no policy to introduce it, remaining fixed at UTC+8:00 every day of the year. Singapore's location approximately one degree north of the equator means daylight hours remain nearly constant across the seasons, removing the original rationale for DST entirely.
Which other major countries share Singapore's time zone?
China, Hong Kong, Taiwan, Malaysia, and Western Australia all operate on the same UTC+8:00 offset as Singapore, though each uses its own regional designation — CST, HKT, CST, MYT, and AWST respectively. Collectively, the UTC+8 bloc represents one of the world's most economically significant time bands.
When does AEDT start and end?
AEDT begins on the first Sunday in October at 02:00 local time, when clocks spring forward one hour from AEST (UTC+10) to AEDT (UTC+11). It ends on the first Sunday in April at 03:00 local time, when clocks fall back to AEST. In 2026, AEDT starts on October 4 and ends on April 5 — following the Southern Hemisphere summer calendar, which runs opposite to DST schedules in Europe and North America.
Is Brisbane on AEDT?
No — Queensland, including Brisbane, does not observe Daylight Saving Time and remains on AEST (UTC+10) year-round. During the AEDT period from October through April, Sydney and Melbourne advance to UTC+11 while Brisbane stays at UTC+10, creating a one-hour gap between cities that share nearly the same longitude and are otherwise in the same time zone for the other six months of the year.
