Hello,
I'm a newcomer here and I'm not sure whether this is the proper forum -- please feel free to re-direct me...

Simple question: if a university where to host a series of lectures in honour of someone (say Fermi, to stick to the Subject line) over the course of a full day, what would be the most appropriate way of referring to the event? Fermi Day or Fermi's Day? More importantly,
why?
Many thanks,
Paulo
