saint 's day ‎(plural saints' days)

A day in a liturgical calendar that is observed in honour of a saint; not necessarily a holiday.
- 1918, W. B. Maxwell, chapter 3, in The Mirror and the Lamp:
  One saint's day in mid-term a certain newly appointed suffragan-bishop came to the school chapel, and there preached on “The Inner Life.” He at once secured attention by his informal method, and when presently the coughing of Jarvis […] interrupted the sermon, he altogether captivated his audience with a remark about cough lozenges being cheap and easily procurable.
