calendar.Calendar

calendar classes

The base calendar class: it prints nothing and instead yields the days of a month as iterators and lists of weeks — raw data for your own output.

Syntax

cal = calendar.Calendar(firstweekday=0)

The first weekday belongs to the instance and ignores setfirstweekday(), which only affects the module-level functions. There is no validation: Calendar(7) silently becomes Monday, while setfirstweekday(7) raises IllegalWeekdayError. itermonthdates() also yields days of the neighbouring months so that weeks are complete, whereas itermonthdays() and monthdayscalendar() put 0 in their place.

Examples

import calendar
cal = calendar.Calendar(firstweekday=calendar.SUNDAY)
print(list(cal.iterweekdays()))  # → [6, 0, 1, 2, 3, 4, 5]
print(cal.monthdayscalendar(2024, 2)[0])  # → [0, 0, 0, 0, 1, 2, 3]

import calendar
days = list(calendar.Calendar().itermonthdates(2024, 2))
print(days[0], days[-1])  # → 2024-01-29 2024-03-03 — соседние месяцы тоже
print(len(days))  # → 35

import calendar
print(calendar.Calendar(7).firstweekday)  # → 0 — без ошибки, по модулю 7
