Cal displays a simple calendar in traditional format and ncal offers an alternative layout, more options and the date of easter. The new format is a little cramped but it makes a year fit on a 25x80 terminal. If arguments are not speci- fied, the current month is displayed.

The options are as follows

• J Display Julian Calendar, if combined with the -eoption, display date of easter according to theJulian Calendar.

• eDisplay date of easter (for western churches).-jDisplay Julian days (days one-based, numbered fromJanuary 1).-oDisplay date of orthodox easter (Greek and !RussianOrthodox?
