Building html calendar view using django

I am trying to build a calendar view using django and trying to avoid writing any html tags inside my view. I found a code that helped me get there, 

from datetime import date, datetime, timedelta, time
import calendar

year=2011
month=12
change=None

# init variables
cal = calendar.Calendar()
month_days = cal.itermonthdays(year, month)
lst = [[]]
week = 0

# make month lists containing list of days for each week
# each day tuple will contain list of entries and 'current' indicator
for day in month_days:
    lst[week].append((day))
    if len(lst[week]) == 7:
        lst.append([])
        week += 1

and in my view, i did the following

<div class="calendar_panel_bottom_noborder">
    <span class="month">Juny 2011</span>
    <span class="day_name">S</span>
    <span class="day_name">M</span>
    <span class="day_name">T</span>
    <span class="day_name">W</span>
    <span class="day_name">T</span>
    <span class="day_name">F</span>
    <span class="day_name">S</span>
    {% for week in month_days %}

        {% for day in week %}
            <span class="date">{{ day }}</span>
        {% endfor %}

    {% endfor %}
    <div class="clear"></div>


</div>

Now, the above code is printing the calendar as per the month and year parameters but they are appearing wrong. When I compare it with the calendar, using december 2011, the first day of the month starts at thursday while in calendar its starting on wednesday. can anyone help point out what I did wrong here?

UPDATE

It seems like the problem is coming from itermonthdays. I tried to do the following

>>> month_days = cal.itermonthdays(2011, 12)
>>> for day in month_days:
...  print day
... 
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

I don't know if I should change some sort of a settings or initiate the class differently. But, the output should start with 4 zeros and end with none based on my PC calendar it shows that december 2011 starts on a thursday which is the 5th day of the week therefore there should be 4 zeros before the count starts. hmm any advice on how i can tackle this issue?

I recently made a calendar to display latest month days

views.py
def index(request):
    x=str(datetime.now())
    d0 = datetime(year=date.fromisoformat(x.split(' ')[0]).year, month=date.fromisoformat(x.split(' ')[0]).month, day=1)
    d1 = datetime(year=date.fromisoformat(x.split(' ')[0]).year, month=date.fromisoformat(x.split(' ')[0]).month+1, day=1)
    cal = Calendar()
    lst = [[]]
    week = 0
    cal.setfirstweekday(0)
    monthly_days = cal.itermonthdates(date.fromisoformat(x.split(' ')[0]).year, date.fromisoformat(x.split(' ')[0]).month)
    month1=date.fromisoformat(x.split(' ')[0]).month
    year1=date.fromisoformat(x.split(' ')[0]).year
    for day in monthly_days:
        if len(lst[week])<7:
            if int(day.strftime('%m'))!=int(str(month1)):
                lst[week].append(' ')
            else:
                lst[week].append(day.strftime('%d'))
        else:
            week+=1
            if int(day.strftime('%m'))!=int(str(month1)):
                lst.append([' '])
            else:
                lst.append([day.strftime('%d')])
    return render(request,'base.html',{'monthly_days':lst})

base.html

<body>
    <h1>
        Hi!!!!
    </h1>
    <h2>
        Welcome to Calendar
    </h2>
        <div>
            <table>
                <tr>
                    <td><span class="day_name">M</span></td>
                    <td><span class="day_name">T</span></td>
                    <td><span class="day_name">W</span></td>
                    <td><span class="day_name">T</span></td>
                    <td><span class="day_name">F</span></td>
                    <td><span class="day_name">S</span></td>
                    <td><span class="day_name">S</span></td>
                </tr>
                {% for week in monthly_days %}
                    <tr>
                    {% for day in week %}
                        <td><span class="date">{{ day }}</span></td>
                    {% endfor %}
                    </tr>
                {% endfor %}
            </table>
        </div>
</body>

This is for a tabular format

You need to include

cal.setfirstweekday(6)

before 

monthdays = ...

According to python documentation, ...

By default, these calendars have Monday as the first day of the week, and Sunday as the last (the European convention).

It looks to me like your problem is simply that itermonthdays starts with Monday instead of Sunday. You can confirm this by temporarily replacing

itermonthdays

with

itermonthdates

and

lst[week].append(day)

with

lst[week].append(day.strftime("%A")))

This should temporarily replace day numbers with day of the week names.

Edit: One possible solution to your problem is to initialize lst to [[0]] and then set lst=lst[:-1] at the end of your loop.
