Morphology

January + one

A B1 learner who knows 'January' and 'one' will transparently interpret 'January 1' as the first day of January (a compositional date expression). However, the specific identification of that date as a Christian religious holiday (e.g., Solemnity of Mary or Circumcision) requires cultural/encyclopedic knowledge beyond the constituents, so the full listed meaning is not fully derivable.

Etymology

January 1 may come from the Roman god Janus, who had two faces and looked both backward and forward; people chose his day to mark a new start. That's why we think of January 1 as 'New Year's Day' and make resolutions or celebrate with fireworks.
