red-letter days

Calendar's highlighted moments

Red-letter days are dates of special significance or memorable occasions.

The phrase comes from the calendar practice of printing saints' days and church festivals in red ink.

Any particularly happy or important day qualifies: Our wedding was a red-letter day.

Getting that job offer was one of the red-letter days of my life.
