[date_sub year="4"] returns: 01.10.2010
[date_sub day="1" month="3" year="4"] returns: 30.06.2010

Suppose today is the 01.10.2014

[date_add day="1"] returns: 02.10.2014
[date_add month="3"] returns: 01.01.2015
[date_add year="4"] returns: 01.10.2018
[date_add day="1" month="3" year="4"] returns: 02.01.2018

Displaying of certain date parts:

It is also possible to only impersonate one part of the date, for example, only the day
This is specified with the “show-parameter”.
Suppose today is the 01.10.2014

[date_add day="1" show="dayonly"] returns: 02
[date_add month="3" show="monthonly"] returns: 01
[date_add year="4" show="yearonly"] returns: 2018
[date_sub day="1" show="dayonly"].[date_sub month="3" show="monthonly"] returns: 30.07
[date_add year="0" show="yearonly"]-[date_add month="1" show="monthonly"]-[date_add day="1" show="dayonly"] returns: 2014-11-02

Returning a special date in your own format:

It is also possible to impersonate a special date, in your desired format. This is specified with the format-parameter.
