Sydney’s day hours stretch from 49 minutes in June to 72 minutes at Christmas
Sydney sits at 33.9° south, far enough from the equator for the seasons to pull the planetary hours well away from sixty minutes.
Daylight saving moves the clock times more than the seasons do. Sydney keeps AEST (UTC+10) through winter and AEDT (UTC+11) from the first Sunday in October to the first Sunday in April. That puts the latest sunrise of the year at about 07:07 in early April, just before the clocks go back, and the earliest at about 05:32 in early October, just before they go forward. Sunset runs from 16:52 in early June to 20:09 on New Year’s Day.
The first planetary hour of every day begins at sunrise, so in Sydney the Moon’s hour that opens a Monday can start anywhere from 05:32 to 07:07 on the clock, depending on the month.
| Date | Sunrise | Sunset | Day hour | Night hour |
|---|---|---|---|---|
| 20 March | 06:57 | 19:07 | 61 min | 59 min |
| 21 June | 06:59 | 16:53 | 49 min | 71 min |
| 23 September | 05:45 | 17:51 | 61 min | 59 min |
| 21 December | 05:40 | 20:05 | 72 min | 48 min |
Times are local clock times from this calculator, with daylight saving applied where Sydney uses it. Each planetary hour is one twelfth of the daylight or one twelfth of the night, so these two lengths set every hour of the day.
Born in Sydney? Enter your birth date and time to see your hour
Leave the city on Sydney, set your birth date and type your birth time into the time field. The panel names your hour and the dial turns to the planetary day you were born in. New South Wales has observed daylight saving each summer since 1971, and the calculator applies the clock rules that were in force on your birth date. A birth before sunrise belongs to the night of the previous day, and the panel tells you when that applies.
