Calendar printing functions

Note when comparing these calendars to the ones printed by cal(1): By default, these calendars have Monday as the first day of the week, and Sunday as the last (the European convention). Use setfirstweekday() to set the first day of the week (0=Monday, 6=Sunday).

class calendar.Calendar(firstweekday=0)

Bases: object

Base calendar class. This class doesn’t do any formatting. It simply provides data to subclasses.

property firstweekday
getfirstweekday()
itermonthdates(year, month)

Return an iterator for one month. The iterator will yield datetime.date values and will always iterate through complete weeks, so it will yield dates outside the specified month.

itermonthdays(year, month)

Like itermonthdates(), but will yield day numbers. For days outside the specified month the day number is 0.

itermonthdays2(year, month)

Like itermonthdates(), but will yield (day number, weekday number) tuples. For days outside the specified month the day number is 0.

itermonthdays3(year, month)

Like itermonthdates(), but will yield (year, month, day) tuples. Can be used for dates outside of datetime.date range.

itermonthdays4(year, month)

Like itermonthdates(), but will yield (year, month, day, day_of_week) tuples. Can be used for dates outside of datetime.date range.

iterweekdays()

Return an iterator for one week of weekday numbers starting with the configured first one.

monthdatescalendar(year, month)

Return a matrix (list of lists) representing a month’s calendar. Each row represents a week; week entries are datetime.date values.

monthdays2calendar(year, month)

Return a matrix representing a month’s calendar. Each row represents a week; week entries are (day number, weekday number) tuples. Day numbers outside this month are zero.

monthdayscalendar(year, month)

Return a matrix representing a month’s calendar. Each row represents a week; days outside this month are zero.

setfirstweekday(firstweekday)
yeardatescalendar(year, width=3)

Return the data for the specified year ready for formatting. The return value is a list of month rows. Each month row contains up to width months. Each month contains between 4 and 6 weeks and each week contains 1-7 days. Days are datetime.date objects.

yeardays2calendar(year, width=3)

Return the data for the specified year ready for formatting (similar to yeardatescalendar()). Entries in the week lists are (day number, weekday number) tuples. Day numbers outside this month are zero.

yeardayscalendar(year, width=3)

Return the data for the specified year ready for formatting (similar to yeardatescalendar()). Entries in the week lists are day numbers. Day numbers outside this month are zero.
