From January 1, 3rd, we switched to the new Western calendar. Because most countries use the new calendar, the calendar of this month is removed for 10 days. Therefore, the calendar of this month is somewhat different. Before that, it was an old Western calendar.
Option:
-M: displayed on Monday as the first day of each week.
-J: displayed in the calendar of Caesar, that is, the number of days from January 1, January 1.
