Time Difference Between Singapore and Sydney
Sydney is 2h ahead of Singapore in standard time, and 3h ahead while Sydney is on daylight saving time.
Singapore keeps the same clock all year. Sydney clocks move forward on the first Sunday of October and back on the first Sunday of April. The figures above cover each part of the year. They do not come from the offset on the day the site was built. The live clocks use the current time.
Working Hours Overlap
For each hour of Singapore's working day (9:00-18:00), here is the corresponding local time in Sydney. Rows highlighted green fall within standard working hours (9:00-18:00) in both cities. Each block is one part of the year, so the table does not change with the day this page was built.

Working Across Singapore and Sydney
This looks like an easy pair, and the clock agrees, right up until a standing 5 PM Singapore call slides into Sydney's evening. Singapore never changes its clock. Sydney does, in the opposite season from Europe and the US. While Sydney is on daylight time, from the first Sunday of October until the first Sunday of April, Sydney is three hours ahead, so 9 AM in Singapore is noon in Sydney. While Sydney is on standard time, from the first Sunday of April until the first Sunday of October, the gap is two hours and that 9 AM Singapore call is 11 AM in Sydney.
The hour that hurts is the late one. 5 PM in Singapore is 8 PM in Sydney during the three-hour setting and 7 PM during the two-hour setting. Both are after a normal Sydney office has thinned out. Keep the live call in Singapore's morning, which is late morning or noon in Sydney, and let it drift by an hour twice a year instead of pinning it to Sydney's end of day. A recurring invite created in Singapore time holds the Singapore hour and moves Sydney. One created in Sydney time does the reverse. Say which one you meant.
The nonstop is about eight hours, a full night or a full day, for a two- or three-hour change. That is a mild shift and a tiring seat. Most people are fine by the second morning if they do not nap the whole arrival afternoon. January is the other catch. Singapore works. A lot of Sydney takes leave from Christmas through the middle of January. A planning week set for the first week of the year will find one side of this pair missing.

- Scheduling with Sydney from the US, the UK, or Singapore
Sydney's clock moves in the opposite season, so the gap with New York, San Francisco, London, and Singapore has more than two settings. Which hour survives, and why January is a bad month to pretend otherwise.
- The week the clocks change: a checklist
What to check the week a region springs forward or falls back: recurring meetings, on-call handoffs, local-time cron jobs, business-hour SLAs, and the hour that happens twice or not at all.
