What it is

The gate of heaven. The sun, moon and planets pass between its two stars.

In the almanac

The almanac gives each day one mansion in a fixed cycle. Xie Ji Bian Fang Shu traces the day-by-day count to an old Western Regions text on the seven planets. The Building row is from the Yu Xia Ji, which rates each mansion for building work.
