  11      it has two parameter: week_start, which allows you two choose what day is the<BR />
  12      first day a week (default is 1 (Monday). Sunday is 0, Monday is 1, ...) and <BR />
  13      locale, which can be used to force the script to another locale (ie de_DE for<BR /> 
  14      German, etc.). Default locale is whatever your server has been set to use as <BR />
  15      default.
