Solar terms are astronomical, not lunar, so the date shifts by at most a day between years.
What it marks
The longest day. Yang energy peaks — and by the logic that runs through the whole almanac, a peak is also a turning point. From here the light shortens.
Traditionally favours
- celebration
- acknowledging a high point
- beginning to consolidate
Treated as a hinge rather than a plateau. Traditional advice is to bank gains rather than push for more.
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.
