Properly gathering, vetting and maintaining other kinds of locale 
information is also a huge task - so that part is not much different.

Many civic holidays in most countries seem to reoccur annually on a 
given date (or often on the following day if the date falls on a 
weekend). These holidays shouldn't be difficult to calculate. However 
the dates for those holidays which are based on religious occasions 
often seem to be based on older (often complex) calendars - and to work 
these dates out  one may first need to figure out a way of accurately 
calculating these calendars if they are not already implemented.

Of course it my not be possible to calculate with accuracy those 
holidays whose dates are dependent on the time at which someone at a 
given location first sees some particular astronomical phenomena.
