Today, October 17, 2026, the ruler is Saturn. In Sydney the Sun rises at 06:11 and sets at 19:10: each daytime planetary hour lasts 65 minutes and each night hour 55.
This is how hours were counted before clocks: with an astrolabe. On the rim, the 24 unequal hours (I to XII by day, I to XII by night). Inside, the sky at that moment: the centre is the highest point, the gold circle is the horizon and whatever lies outside is below the ground. North at the top, east on the left. The stone with a halo rules the hour. Turn the gold handle to travel through the day.

The day’s most beautiful light for photos and walks: blue hour with the Sun 6° to 4° below the horizon; golden hour from 4° below to 6° above.
