Solar Terms Worksheet: How to Record Dates, Weather, and Seasonal Evidence

Use a solar terms worksheet as a local observation diary: record the calendar event first, then what you actually see. Keep a blank result when no observation was made instead of filling it with a traditional weather saying.

Repeat observations consistently

Visit the same location at roughly the same time over several days. Note a change in method, such as moving a thermometer indoors. This makes a diary easier to compare without presenting a short exercise as a scientific climate record.

Compare without forcing agreement

A dew-free morning near White Dew is a valid observation. The calendar definition depends on the Sun’s position; visible dew depends on local conditions. Use the separate 24-term worksheet for a whole-year classroom table.

Calendar sources

Hong Kong Observatory: term names and solar longitudes; 2026 Gregorian–lunar conversion table; date and time notes (Hong Kong Time, UTC+8). The calendar sources establish astronomical timing and terminology; they do not verify regional customs.

Frequently Asked Questions

How should dates be recorded?

Record the year, term name, source and timezone. Hong Kong Observatory dates use Hong Kong Time (UTC+8). A date from another timezone can differ near midnight.

Should local observations match the term’s name?

No. Record what actually happened at the named location, including an absence of dew, rain or snow. A term name is not an observation.
