===Solstice terms in East Asia===
{{Main|Xiazhi|Dongzhi (solar term)}}

The traditional East Asian calendars divide a year into 24 [[solar term]]s (節氣). '''Xiàzhì''' <small>([[Pinyin|pīnyīn]])</small> or '''Geshi''' <small>([[Romanization of Japanese|rōmaji]])</small> ({{CJKV|t=夏至|s=夏至|j=夏至|k=하지(Haji)|Tibetan=དབྱར་ཉི་ལྡོག|v=Hạ chí|l=''summer's extreme''}}) is the 10th solar term, and marks the '''summer solstice'''. It begins when the Sun reaches the [[celestial longitude]] of 90° (around 21 June) and ends when the Sun reaches the longitude of 105° (around 7 July). Xiàzhì more often refers in particular to the day when the Sun is exactly at the celestial longitude of 90°.

'''Dōngzhì''' <small>([[Pinyin|pīnyīn]])</small> or '''Tōji''' <small>([[Romanization of Japanese|rōmaji]])</small> ({{CJKV|t=冬至|s=冬至|j=冬至|k=동지(Dongji)|Tibetan= དགུན་ཉི་ལྡོག|v=Đông chí|l=''winter's extreme''}}) is the 22nd solar term, and marks the '''winter solstice'''. It begins when the Sun reaches the [[celestial longitude]] of 270° (around 23 December) and ends when the Sun reaches the longitude of 285° (around 5 January). Dōngzhì more often refers in particular to the day when the Sun is exactly at the celestial longitude of 270°.

The solstices (as well as the [[equinox]]es) mark the middle of the seasons in East Asian calendars. Here, the Chinese character [[wikt:至|至]] means "extreme", so the terms for the solstices directly signify the summits of summer and winter.
