19 January

19 January (the Nineteenth of January, January 19th, &c.) is the nineteenth 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 19 January is followed by either 346 days or 347 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 20 January and the date that precedes it is 18 January.

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