Hi Dan,

I normally recommend to deal with them as types, as long as they are 
celebrated as a social event in the widest sense, which is the 
14 of July is not even an event in that sense, but a component of the 
system describing dates. We can introduce all 14s of July as another 
temporal construct, in addition to time-span. I can check for the 
respective good practice of modeling them.
