22 January

22 January (the Twenty-Second of January, January 22nd, &c.) is the twenty-second day of the year under the Gregorian calendar, as first promulgated by Pope Gregory XIII, Bishop of Rome, in 1582 A.D., as well as the earlier Julian calendar, as first promulgated by Julius Caesar in 45 B.C. The date of 22 January is followed by either 343 days or 344 days during leap years, which are calculated differently in Gregorian and Julian calendars; in both calendars, regardless of its leap year status, the date that follows is 23 January and the date that precedes it is 21 January.

Note that for the purposes of the following indices, the Gregorian date trumps the Julian date, unless otherwise indicated.
