in_future
Tests if a date is in the future.
Tests if the value is a date and in the future. 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 will be undefined.
For example:
{% if value|in_future %}That day has yet to come.{% endif %}
This outputs “That day has yet to come.” if the value is a date and in the future.
