cal - print calendar
cal [ month ] year
_C_a_l prints a calendar for the specified year. If a month is also specified, a calendar just for that month is printed. _Y_e_a_r can be between 1 and 9999. The _m_o_n_t_h is a number between 1 and 12. The calendar produced is that for England and her colonies.
Try September 1752.
The year is always considered to start in January even though this is historically naive. Beware that `cal 78' refers to the early Christian era, not the 20th century.
