CAL(1) BSD Reference Manual CAL(1) NNAAMMEE ccaall - displays a calendar SSYYNNOOPPSSIISS ccaall [--jjyy] [_m_o_n_t_h [_y_e_a_r]] DDEESSCCRRIIPPTTIIOONN CCaall displays a simple calendar. If arguments are not specified, the cur- rent month is displayed. The options are as follows: --jj Display julian dates (days one-based, numbered from January 1). --yy Display a calendar for the current year. A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: ``cal 89'' will _n_o_t display a calendar for 1989. Two parameters denote the month (1 - 12) and year. If no pa- rameters are specified, the current month's calendar is displayed. A year starts on Jan 1. The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. By this time, most countries had recognized the reforma- tion (although a few did not recognize it until the early 1900's.) Ten days following that date were eliminated by the reformation, so the cal- endar for that month is a bit unusual.
