Comment 25 for bug 174672

For both lightning and sunbird, please implement an extra option when adding a new calendar. Next to 'On My Computer' and 'On the Network', offer an option called 'National Holidays on the Network'. This will offer the user to select 0 or more calendars from http://www.mozilla.org/projects/calendar/holidays.html

Implementing this features will allow more people to use the same shared but read only holiday calendars which are managed in a central place, leaving less margin's for errors in common data as national holidays.
