How the gap moves through the year

Singapore is 3 hours behind Sydney for about 6 months of the year.

Singapore is 2 hours behind Sydney for about 6 months of the year.

From the first Sunday in April (when Sydney falls back), Singapore is 2 hours behind Sydney.

From the first Sunday in October (when Sydney moves forward), Singapore is 3 hours behind Sydney.

Sydney moves its clocks forward one hour on the first Sunday in October at 2:00 am local time and back on the first Sunday in April at 3:00 am, switching between Australian Eastern Standard Time (UTC+10) and Australian Eastern Daylight Time (UTC+11).

Singapore does not change its clocks: it stays on UTC+8 (Singapore Standard Time) all year.

Next clock change for this pair, as of when this page was built (2026-10-20): Sydney falls back on Sun 4 April 2027.

Everything on this page also holds if you swap Sydney for Melbourne, Canberra or Hobart, or Singapore for Shanghai, Beijing, Guangzhou, Shenzhen or Taipei — those cities follow exactly the same clock all year.

Common mistakes with Sydney and Singapore

  • Forgetting that the gap changes even though Singapore never touches its clocks: Sydney does, so a meeting fixed in Singapore time moves by an hour for people in Sydney.
  • Writing “GMT+11” all year for Sydney. In summer the zone is Australian Eastern Standard Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
