I have used the following in my Django based website <a href="http://pmtboyshostelraipur.pythonanywhere.com/" rel="nofollow noreferrer">http://pmtboyshostelraipur.pythonanywhere.com/</a> which works fine as expected (Maybe, by the time you're reading this post, it would have stopped working because that's a free hosting so just try in code and see).

<pre><code>{% now 'Y' %}
</code></pre>

You can visit &amp; see it in the footer part where I have displayed the current year using the below code(CSS part is omitted so use your own).

<pre><code>&lt;footer class="container-fluid" id="footer"&gt;
 &lt;center&gt;
 &lt;p&gt;
 &amp;copy;
 {% now 'Y' %}, 
 PMT Boys hostel &lt;br&gt; 
 All rights reserved
 &lt;/p&gt;
 &lt;/center&gt;
&lt;/footer&gt;
</code></pre>

And it is displaying the following centred text in my website's footer.

<pre><code>©2018, PMT Boys hostel

blocks|key|658231|text|在我的模板中，除了当前年份之外，我还需要一个包含20个值的信用卡到期年份下拉列表(从当前年份开始)。select值需要是2位数，显示字符串需要是4位数。为了避免复杂的模板代码，我编写了这个简单的模板标记：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|658232|@register.filter
def+add_current_year(int_value,+digits=4):
++++if+digits+==+2:

++++return+'%25d'+%25+(int_value+%2B+datetime.datetime.now().year)|code-block|syntax|javascript|658233|并以以下方式使用它：|658234|<select+name="card_exp_year">
++++{%25+for+i+in+'iiiiiiiiiiiiiiiiiiii'+%25}
++++<option+value="{{+forloop.counter0%7Cadd_current_year:2+}}">{{+forloop.counter0%7Cadd_current_year:4+}}</option>
++++{%25+endfor+%25}
</select>|658235|entityMap^0|1E|6|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|P|$]]

In my template, aside from the current year, I needed a credit card expiration year dropdown with 20 values (starting with the current year). The <code>select</code> values needed to be 2 digits and the display strings 4 digits. To avoid complex template code, I wrote this simple template tag:

<pre><code>@register.filter
def add_current_year(int_value, digits=4):
 if digits == 2:
 return '%02d' % (int_value + datetime.datetime.now().year - 2000)
 return '%d' % (int_value + datetime.datetime.now().year)
</code></pre>

And used it in the following manner:

<pre><code>&lt;select name="card_exp_year"&gt;
 {% for i in 'iiiiiiiiiiiiiiiiiiii' %}
 &lt;option value="{{ forloop.counter0|add_current_year:2 }}"&gt;{{ forloop.counter0|add_current_year:4 }}&lt;/option&gt;
 {% endfor %}
&lt;/select&gt;
</code></pre>

What is the inbuilt template tag to display the present year dynamically. Like "2011" what would be the template tag to display that?

How to display the current year in a Django template?

Django

动态显示当年的内置模板标记是什么。像"2011“，什么是模板标签来显示它？
