Script Summary: Userscript to replace dates in gmail with links to google calendar
This userscript recognizes dates and replaces them with links to Google Calendar. So, suppose someone sends you an invitation for a particular date, it will be transformed to a link to that day in Google Calendar.
Currently the following date formats are supported (more to come, write down your (language-specific) requests in the comments!):
September 1st (Year will be determined)
September 1st 2009
1 September 2007
