Sydney & Singapore Time Difference
🕐 Live Timezone Overlap: Sydney & Singapore
Sydney and Singapore sit just 2 hours apart, making this one of the more manageable time gaps in the Asia-Pacific region. Singapore is behind Sydney. That means a 9am start in Singapore corresponds to 11am in Sydney, giving both cities a generous 7-hour overlap within standard working hours. For teams coordinating across these two cities, the afternoon block is where most of the scheduling action happens.
Time Difference: Sydney and Singapore
Singapore is currently 2 hours behind Sydney. The live offsets are Sydney UTC+10 and Singapore UTC+8. Sydney observes daylight saving and Singapore does not, so the offset shifts twice a year if both sides aren't already aligned.
Sydney currently runs at UTC+10 (AEST). It observes daylight saving time, shifting to UTC+11 (AEDT) from the first Sunday in October to the first Sunday in April. Singapore runs UTC+8 year-round with no DST at all. When Sydney moves to AEDT, the gap between the two cities widens from 2 hours to 3 hours. That shift happens twice a year and directly affects any standing meeting cadence between Sydney and Singapore teams.
Best Times to Meet
The 7-hour overlap runs from 11am to 6pm in Sydney and 9am to 4pm in Singapore. Inside that 7-hour window, the cleanest slot is typically 11am to 2pm Sydney time (9am to noon Singapore). Singapore offices treat 9am to 6pm as firm working hours, and Singapore-based APAC headquarters often fill afternoons with regional calls. Booking early in the overlap keeps Singapore participants fresh and avoids Sydney colleagues being pushed into a late-afternoon finish.

Tips for Scheduling Across Sydney and Singapore
- When Sydney shifts to AEDT in October, update recurring Singapore calls immediately: the gap grows to 3 hours.
- Book meetings before 2pm Singapore time to keep all participants comfortably inside core working hours in both cities.
- Avoid scheduling Sydney-Singapore calls between Christmas and 26 January: Sydney offices run on skeleton staff during that period.
- Chinese New Year brings extended absences in Singapore, so avoid scheduling critical calls in late January or early February.
- Sydney works ahead of most of the world: confirm whether a Sydney date is still the previous calendar day for any third city on the call.
Public Holidays and Working Weeks
Both Sydney and Singapore follow a standard Monday to Friday working week, with 9am to 6pm as the working day in each city. Key dates to watch: Sydney observes Australia Day on 26 January and ANZAC Day on 25 April. Singapore's Chinese New Year falls in January or February and carries 2 public holidays plus common extended absences. Cross-city meetings should be checked against both calendars, particularly in late January when both cities can be affected simultaneously.
