Understanding Planetary Hours in Shiyan
Planetary hours are an ancient timing system that divides each day into 24 unequal periods — 12 during daylight and 12 at night — each governed by one of seven classical planets. Unlike clock hours, their length shifts with the seasons: in Shiyan today, each daytime planetary hour lasts about 66 minutes (daylight of 13h 8m ÷ 12). The first hour after sunrise always belongs to the day's ruling planet, and the rest follow the Chaldean order.
Today in Shiyan, sunrise is at 06:05 AM and sunset at 07:13 PM (Asia/Shanghai). The day ruler is Sun — the planet that governs Sunday and sets the tone for the day. Below you'll find every planetary hour for Shiyan today, with the ruling planet and exact start time for each period.

How We Calculate Planetary Hours for Shiyan
We pull precise astronomical sunrise (06:05 AM) and sunset (07:13 PM) times for Shiyan's exact coordinates, then divide the daylight window by 12 to get the length of each daytime planetary hour (about 66 minutes today). The night period — sunset to the next morning's sunrise — is split into 12 in the same way.
The first hour after sunrise is assigned to the day ruler (Sun), and subsequent hours follow the Chaldean order. Because Shiyan's sunrise and sunset shift daily, these hours are recalculated fresh every time you load this page.
