Open Meeting Planner →What Singapore and Sydney have in common is technology; that is the usual reason for a call between them. The gap is 3 hours, with Sydney the one whose clock reads later.
The working week is Monday to Friday on both sides: roughly 09:00–18:00 in Singapore and 09:00–17:30 in Sydney. Watch for Chinese New Year (two days in January or February) and Hari Raya Puasa (end of Ramadan) in Singapore and Australia Day (26 January) and Anzac Day (25 April) in Sydney. Replies slow in Singapore during Chinese New Year week and in Sydney during Christmas to the end of January, the summer holidays.
Book between 09:00–14:00 in Singapore (12:00–17:00 in Sydney); 5 hours of overlap means neither side takes the call early or late. Only Sydney changes its clocks, so the gap shifts by an hour twice a year while Singapore stays put.
Sydney is 3 hours ahead of Singapore. The gap changes by an hour around the clock changes.
