同期 (tóng qī) — the same period (in a different year, e.g., same quarter or month); the same time (for events happening concurrently)

Definition

同期 names a time point in another reference frame — e.g. last year's same quarter — so it always pairs with a comparison. 同步 is the verb 'to sync'; 平行 covers parallel/equal-rank senses that 同期 does not.

noun
