How the date 138 years ago is calculated
To go back or forward a whole number of years, keep the same month and day and change only the year. The one exception is February 29: if the target year is not a leap year, the date moves to February 28, the last day of that month. Because the calendar repeats its weekday pattern only every 28 years or so, the day of the week usually changes.
