Relative Date Token (next month)?

Hello,

could somebody please describe me, if and how I could use a token for a
relative date inside a menu title (and path)? For the current month of a
calender I could use the menu token module, but I don´t know how to get
the name of the following month ('march') working.

Is there a possibility to use the relative date funktionality like in views
running inside menu token? ('next month' = 'March')

Thank you very much in advance!

Anton
