Singapore to Sydney: time difference and meeting times
Everything you need to schedule between Singapore and Sydney — the current offset, both cities' daylight saving dates, and the hour-by-hour overlap of their working days.
7 hours of full overlap. Both cities are inside normal working hours (09:00–17:59 local) at 01:00–08:00 UTC. Any hour in that range works for both sides without anyone starting early or finishing late.

Daylight saving
Singapore does not observe daylight saving — this offset is fixed all year. Sydney next moves its clocks forward on 4 October 2026, to UTC+11.
Only one side changes its clocks
Sydney observes daylight saving and Singapore does not. The difference between these two cities is therefore not constant — it changes twice a year, entirely because of the Sydney side. A recurring meeting fixed to local time in Singapore will appear to move by an hour in Sydney, and vice versa.
Scheduling across this corridor
Southeast Asia and eastern Australia are a few hours apart with a genuinely usable shared day: the Australian afternoon lands squarely inside the Southeast Asian working day. Singapore and Jakarta hold fixed offsets while Sydney shifts for daylight saving, so the gap is an hour wider during the southern summer than during the southern winter.
About Singapore
Singapore holds a fixed offset year-round with no daylight saving, eight hours ahead of UTC — a notable detail given its longitude, since the country sits further east on the clock than the sun would suggest. Its position makes it the standard meeting point for Asian regional business, with a working day that reaches both the European morning and the Australian afternoon.
About Sydney
Sydney observes daylight saving on the southern-hemisphere schedule, moving forward in October and back in April — the opposite of the northern hemisphere. For part of the year the two hemispheres are both on summer time, and the gap between Sydney and Europe or North America changes twice as much across the year as people expect. Australia is not a single timezone: the eastern states, South Australia and Western Australia all differ, and not all of them observe daylight saving.
