Depending on which Email client you are using, procedure may be different. For Outlook 2000, select tools dropdown menu, select options. Within Preference Tab, select Calender options, and Add Holidays. You can select Germany, US, Mexico, and alltheir holidays will appear to the calender for that local machine.
