add to date value in velocity

It is necessary to retrieve the date and then, resourcing to JavaScript, add/remove days to a date.

The official Velocity's documentation highlights all methods available for date manipulation
velocity.apache.org/tools/releases/1.3/javadoc/org/apache/velocity/tools/generic/DateTool.html

Thanks Breno

do you have an example of "resourcing to JavaScript"

The date tool has no methods on doing math on dates

Keen to see an example too
