Occasion to dye eggs (6)
I believe the answer is:
easter
'occasion to dye eggs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for easter that I've seen before include "Egg-rolling time" , "Teaser about Christian festival" , "Annual religious festival" , "Sort of tide" , "Festival after Lent" .)
