Handling date through some type of in-built calendar is central to any programming language. Here we see how to handle various date related functions available in python’s in-built library.
firstweekday()
Using this function we find the number assigned to the first day of the week.
Example
import calendar
# print starting day number
print("The number of the first day in calendar is : ")
print(calendar.firstweekday())Output
Running the above code gives us the following result −
The number of the first day in calendar is : 0
leapdays(StartYear, EndYear)
This function is used to calculate the number of leap days between two given years.
Example
import calendar
print("The number of leap days between 1980 and 2015:")
print (calendar.leapdays(1980, 2015))Output
Running the above code gives us the following result −
The number of leap days between 1980 and 2015: 9
HTMLCalendar
This function allows you to print HTML formatted calendar for a month.
Example
import calendar hc = calendar.HTMLCalendar(calendar.TUESDAY) a = hc.formatmonth(2019, 3) print(a)
Output
Running the above code gives us the following result −
<table border="0" cellpadding="0" cellspacing="0" class="month"> <tr><th colspan="7" class="month">March 2019</th></tr> <tr><th class="tue">Tue</th><th class="wed">Wed</th><th class="thu">Thu</th> <th class="fri">Fri</th><th class="sat">Sat</th><th class="sun">Sun</th><th class="mon">Mon</th></tr> <tr><td class="noday"> </td><td class="noday"> </td><td class="noday"> </td> <td class="fri">1</td><td class="sat">2</td><td class="sun">3</td><td class="mon">4</td></tr> <tr><td class="tue">5</td><td class="wed">6</td><td class="thu">7</td><td class="fri">8</td> <td class="sat">9</td><td class="sun">10</td><td class="mon">11</td></tr> <tr><td class="tue">12</td> <td class="wed">13</td><td class="thu">14</td><td class="fri">15</td><td class="sat">16</td> <td class="sun">17</td><td class="mon">18</td></tr> <tr><td class="tue">19</td><td class="wed">20</td> <td class="thu">21</td><td class="fri">22</td><td class="sat">23</td><td class="sun">24</td> <td class="mon">25</td></tr> <tr><td class="tue">26</td><td class="wed">27</td><td class="thu">28</td> <td class="fri">29</td><td class="sat">30</td><td class="sun">31</td><td class="noday"> </td> </tr></table>
