how to get days diffrence from current day.
tweetedAt: "2015-02-22 09:56:42".

twig

{% for key,value in data.about %}
{% set tweets_date=(value.tweetedAt|date).date("now").format('%a') %}
{% endfor %}

I have also tried

{% set dd='now'|date('d-m-Y') %}
{% set tweets_date=(value.tweetedAt|date).dd.format('%a') %}

Finally I tried but its giving error:

A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses (unexpected token "punctuation" of value "{"

{% set difference = {{ date("m/d/Y") }}.diff(date(value.tweetedAt)) %}
{% set leftDays = difference.days %}

Error:

<span class="small light_grey">{{tweets_date}}</span>

I tried this code and it works.

{% set difference = date(value.tweetedAt|date('Y/m/d')).diff(date('now'|date('Y/m/d'))) %}
{% set leftDays = difference.days %}

You need use filters not methods on your objects. And you need to use time_diff filter:

{%set tweets_date=value.tweetedAt|time_diff %}

To make it work you need first install twig-extensions via composer:

composer require twig/extensions

and then include it in service container with appropriate tag:

services:
    app.twig.extension.date:
        class:        Twig_Extensions_Extension_Date
        tags:
             - { name: 'twig.extension' }

回答3:

If the date comes from an entity, you can just:

{{ entity.days }}

And in your entity just implement:

public function getDays()
{
    return $this->date->diff(new DateTime)->format('%a');
}
