Solar terms are a calendar and cultural reference. They are not day-long weather forecasts, and historical or regional practices should not be inferred from a date alone.
How this is calculated
The tool uses the same deterministic calendar library as OrientLore’s festival calendar. It identifies each solar term by the Sun’s longitude and displays the resulting instant in China Standard Time for years 1900–2100.

Frequently asked questions
3 common questions
- Do the solar terms fall on the same date every year?
- They stay near the same part of the Gregorian year, but the exact date and time can shift because each term is defined by the Sun reaching a specified longitude.
- Are the twenty-four solar terms lunar dates?
- No. They track the Sun’s apparent annual motion and form the solar framework within the Chinese lunisolar calendar.
- Which time zone does this tool use?
- All displayed times use China Standard Time, UTC+8. The same instant can have a different clock time or even date in another time zone.
