Key timings for Saturday, July 18
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 Ho Chi Minh City today, each daytime planetary hour lasts about 63 minutes (daylight of 12h 41m ÷ 12). The first hour after sunrise always belongs to the day's ruling planet, and the rest follow the Chaldean order.

We pull precise astronomical sunrise (05:39 AM) and sunset (06:20 PM) times for Ho Chi Minh City's exact coordinates, then divide the daylight window by 12 to get the length of each daytime planetary hour (about 63 minutes today).
