Python calendar module : yeardayscalendar() method

  • Difficulty Level : Hard
  • Last Updated : 12 May, 2021

Calendar module allows to output calendars like program, and provides additional useful functions related to the calendar. Functions and classes defined in Calendar module use an idealized calendar, the current Gregorian calendar extended indefinitely in both directions. 

yeardayscalendar() method in Python is used to get the data for specified year. Entries in the week lists are day numbers. Day numbers outside this month are zero. 

Syntax: yeardayscalendar(year, width)

Parameter: 
year: year of the calendar
width: [Default: 3] number of months in each row. 

Returns: list of day numbers.

Code #1:  

Python3




# Python program to demonstrate working
# of yeardayscalendar() method
 
# importing calendar module
import calendar
 
obj = calendar.Calendar()
 
year = 2016
# default value of width is 3
 
# printing with yeardayscalendar
print(obj.yeardayscalendar(year))

Output: 

[[[[0, 0, 0, 0, 1, 2, 3], [4, 5, 6, 7, 8, 9, 10], [11, 12, 13, 14, 15, 16, 17], [18, 19, 20, 21, 22, 23, 24], [25, 26, 27, 28, 29, 30, 31]], [[1, 2, 3, 4, 5, 6, 7]… 
… 
[[0, 0, 0, 1, 2, 3, 4], [5, 6, 7, 8, 9, 10, 11], [12, 13, 14, 15, 16, 17, 18], [19, 20, 21, 22, 23, 24, 25], [26, 27, 28, 29, 30, 31, 0]]]]

Code #2: iterating the list of weeks  

Python3




# Python program to demonstrate working
# of yeardayscalendar() method
 
# importing calendar module
import calendar
 
obj = calendar.Calendar()
 
# iterating with yeardayscalendar
for day in obj.yeardayscalendar(2018, 1):
    print(day)

Output: 

[[[1, 2, 3, 4, 5, 6, 7], [8, 9, 10, 11, 12, 13, 14], [15, 16, 17, 18, 19, 20, 21], [22, 23, 24, 25, 26, 27, 28], [29, 30, 31, 0, 0, 0, 0]]] 
[[[0, 0, 0, 1, 2, 3, 4], [5, 6, 7, 8, 9, 10, 11], [12, 13, 14, 15, 16, 17, 18], [19, 20, 21, 22, 23, 24, 25], [26, 27, 28, 0, 0, 0, 0]]] 
… 
[[[0, 0, 0, 0, 0, 1, 2], [3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16], [17, 18, 19, 20, 21, 22, 23], [24, 25, 26, 27, 28, 29, 30], [31, 0, 0, 0, 0, 0, 0]]]
