Christmas Day and St Stephen's Day? as for the rest?
I believe the answer is:
holidays
'christmas day and st stephen's' is the definition.
I can't tell whether this defines the answer.
'day? as for the rest?' is the wordplay.
'day? as' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the rest?' becomes 'holiday' (I've seen this before).
's' after 'holiday' is 'HOLIDAYS'.
Can you help me to learn more?
(Other definitions for holidays that I've seen before include "Lidos, yah? (Anag)" , "Is away" , "Leaves" , "Periods of release from work" , "Leisure periods" .)
