in_past
Tests if a date is in the past.
Tests if the value is a date and in the past. The value must be a
tuple of the format {Y,M,D} or {{Y,M,D},{H,I,S}}. When the value is
not a date or datetime, the result is undefined.
For example:
{% if value|in_past %}Those days have gone.{% endif %}
This outputs “Those days have gone.” if the value is a date and in the past.
