时间

时 shí = 日 rì (sun) + 寺 sì (phonetic: a place of regularity; a temple; an official bureau). Time as regulated by the sun — the seasons, the hours of the day. Originally meant "the right season, the right moment." In classical Chinese, 时 carries the sense of timeliness — the right action at the right moment. Confucius' virtue 时中 (timely balance) meant knowing not just what to do but when.

间 jiān/jiàn = 门 mén (gate) + 日 rì (sun). Sunlight coming through a gate — the gap, the interval, the space between. As jiān: space between, room, interval. As jiàn: to separate, to interpose. 时间 together: the intervals between suns — the measured gaps that constitute time.

Classical Chinese time is fundamentally cyclical. The calendar is built on cycles: the 60-year stem-branch cycle (干支 gānzhī), the 12-year zodiac (十二生肖), the 24 solar terms (二十四节气 èrshísì jiéqì). Time turns like a wheel — dynasties rise and fall, seasons return, the Dao moves in circles. This is why Chinese historical writing often uses cyclical frameworks: history rhymes rather than progresses.

Linear time as a concept existed (Buddhism introduced it more sharply, and modernization accelerated it), but the cultural default is still cyclical. 时节 shíjié (season/occasion), 节气 jiéqì (solar term), and 时辰 shíchen (two-hour period in the traditional day-division) all encode time as a returning wheel rather than an arrow.
