Lesser Heat Solar Term Meaning: Summer Heat and Observation Notes

Minor Heat, Xiaoshu (小暑), marks a summer point in the solar-term sequence before Great Heat. In 2026 it falls on July 7 in Hong Kong Time (UTC+8), at a solar longitude of 105°.

Calendar position and meaning

Lesser Heat and Minor Heat refer to Xiaoshu; the Hong Kong Observatory calls it Moderate Heat. These are translations of one term, not separate calendar events.

Seasonal context

The lunar clothing-airing date is not identical to the solar-term date every year. Food proverbs in the source express tradition and taste; they are not evidence of medical benefit.

The seasonal word “summer” here follows the traditional Northern Hemisphere calendar. The Hong Kong Observatory relates many term names to ancient central Chinese weather and agriculture. Local weather and plant development may differ; Southern Hemisphere seasonal timing is reversed.

Regional example and limits

Beijing tourism material identifies lotus-root and ricefield-eel food customs in Nanjing, Jiangsu, around Minor Heat. It also describes clothing-airing practices associated with the sixth day of the sixth lunar month.

Regional example source: read the named account. The account supports the place and practice stated above, not medical benefits or a national rule.

Identifying Lesser Heat on another calendar

Lesser Heat is Xiaoshu, written 小暑. A calendar using Minor Heat or Moderate Heat refers to the same 105° marker. Great Heat is Dashu, 大暑, at 120°, so the two should not be merged just because both English names mention heat.

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.
