Location unspecified when year changes (8)
I believe the answer is:
anywhere
'location unspecified' is the definition.
(I've seen this in another clue)
'when year changes' is the wordplay.
'changes' is an anagram indicator.
'when'+'year'='whenyear'
'whenyear' with letters rearranged gives 'ANYWHERE'.
(Other definitions for anywhere that I've seen before include "At no specified place" , "In no particular place" , "Unspecified place" , "In an unspecified location" , "In whatever place" .)
