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, then the result is undefined.
For example:
{% if value|in_future %}That day has to come.{% endif %}
This outputs “That day has to come.” if the value is a date and in the future.
This is useful in combination with for example the if tag.
