The date on the death certificate says 13 Feb 1923. The actual death date has a write-over making it look like 1922 but the rest of the dates are 1923.
Edit: Just had another look and the dates don't make sense. The doctor said that he attended her Mar 5-13, 1923 but the date of death is Feb 13. Since the burial date is Mar 14, I would say that the actual death date is Mar 13, 1923 and there is an error in the death date.
