Planetary Hours in Sydney Through 2026
Over the year a daytime hour in Sydney runs from 50 minutes around Jun 21 to 72 minutes around Dec 22, a swing of 22 minutes.
South of the equator the seasons run the other way, so Sydney's longest daytime hours fall in December and its shortest in June.
Clocks in Sydney go back an hour on Apr 5 and forward on Oct 4. The planetary hours follow the Sun, so the hours themselves don't move; only their clock times jump by an hour overnight.
By the clock, Sydney's latest sunrise of the year comes on Apr 4 (7:09 AM), the last morning before clocks go back, not on the shortest day.
