set calendar [ ( input | output ) ] <calendar>
The set calendar command sets the calendar that Pyxplot uses to convert dates between calendar dates and Julian Day numbers. Pyxplot uses two separate calendars which may be different: an input calendar for processing dates that the user inputs as calendar dates, and an output calendar that controls how dates are displayed or written on plots. The available calendars are British, French, Greek, Gregorian, Hebrew, Islamic, Jewish, Julian, Muslim, Papal and Russian, where Jewish is an alias for Hebrew and Muslim is an alias for Islamic.
