Brisbane’s first planetary hour can start at 04:44, because Queensland keeps no daylight saving
Queensland stays on AEST (UTC+10) all year. In summer the Sun rises over Brisbane before five, with the earliest sunrise of the year at about 04:44 in late November, and the first planetary hour of the day starts with it. The latest sunrise is about 06:38 in late June. Sunset ranges only from 17:00 in early June to 18:47 in early January.
At 27.5° south, Brisbane’s hours swing less than those of the southern capitals. The longest day hour, near 23 December, runs 69.4 minutes, and the shortest, on 22 June, runs 52.0. A Brisbane night hour stays between about 51 and 68 minutes all year.
Brisbane lies a little east of the 150° meridian that sets Eastern time, so its solar noon falls between 11:31 and 12:02 and the seventh day hour, which begins at solar noon, starts close to midday on the clock. Brisbane is home to the school, and its hours are the calculator’s default when no other city can be found.
| Date | Sunrise | Sunset | Day hour | Night hour |
|---|---|---|---|---|
| 20 March | 05:50 | 18:00 | 61 min | 59 min |
| 21 June | 06:37 | 17:01 | 52 min | 68 min |
| 23 September | 05:37 | 17:44 | 61 min | 59 min |
| 21 December | 04:48 | 18:41 | 69 min | 51 min |
Times are local clock times from this calculator, with daylight saving applied where Brisbane 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 Brisbane? Enter your birth date and time to see your hour
Leave the city on Brisbane, 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. Queensland used daylight saving only in 1971–72 and from 1989 to 1992, and the calculator applies it automatically for birth dates in those summers. A birth before sunrise belongs to the night of the previous day, and the panel tells you when that applies.
