Christmas and Easter? (7)
I believe the answer is:
islands
'christmas and easter?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for islands that I've seen before include "Achill and Aran, say" , "Falkland" , "Land masses with water on both sides" , "man and dogs, say" , "Ibiza, Corfu etc" .)
