Annual calendar (7)
I believe the answer is:
almanac
'annual calendar' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for almanac that I've seen before include "Annual reference book" , "Informative calendar" , "Annual publication giving dates of astronomical and other events" , "Annual publication providing information like Old Moore's" , "Annual publication, Old Moore's perhaps" .)
