End of Lent (6)
I believe the answer is:
easter
'end of lent' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for easter that I've seen before include "Important Christian festival" , "Resurrection festival" , "A terse sort of Spring festival?" , "Teaser about Christian festival" , "Christian celebration of the Resurrection" .)
