  • The passage of time, especially the gradual progression of events or aging over years and months.

Etymology

on’yomi reading nengetsu; formed as a Sino-Japanese compound using the characters 年 and 月; the pronunciation reflects standard on readings for kanji compounds

Composition

  • 年: year
  • 月: month
  • When combined, they express a span of time measured in years and months rather than a specific day.

Usage

Used in formal and written Japanese to denote a duration of time rather than a specific date. It appears in historical summaries, business documents, and biographical narratives; commonly paired with verbs describing passage or accumulation of time.
