How to display current year in Flask template?

I am looking to find out how to output the current year in a Flask template. I know in Django you can use {% now "Y" %}., but is there a Flask equivalent? I have been unable to find anything during my research thus far.

If using Jinja2 is too cumbersome and you are using Jinja2 in a context of a browser that you can simply use Javascript.

Using Simple Javascript

<span id="year"></span>

const year = document.querySelector('#year');
if (year) {
    year.innerHTML = new Date().getFullYear().toString();
}

JavaScript library like moment.js

<script>
document.write(moment("2012-12-31T23:55:13 Z").format('LLLL'));
</script>

Use a template context processor to pass the current date to every template, then render its year attribute. 

from datetime import datetime

@app.context_processor
def inject_now():
    return {'now': datetime.utcnow()}

{{ now.year }}

Or pass the object with render if you don't need it in most templates.

return render_template('show.html', now=datetime.utcnow())

For moment there is Flask Moment. It is powerful like Moment, and easy to use in Flask. To display the year in the user's local time from your Jinja template:

<p>The current year is: {{ moment().format('YYYY') }}.</p>
