Solar terms are astronomical, not lunar, so the date shifts by at most a day between years.

What it marks

Day and night equal again, this time with the balance tipping toward dark. The mirror of the spring equinox, and traditionally associated with the mid-autumn harvest.

Traditionally favours

  • fair dealing
  • closing agreements
  • family gatherings
  • balance

Like its spring counterpart, a favoured window for settling things evenly between parties.

These are the tradition’s tendencies, not guarantees — and a solar term describes a stretch of weeks, so for a specific day check today’s almanac, which reads the day’s own 宜 and 忌.
