Date for Roman candles to be ordered (7)
I believe the answer is:
calends
'date for roman candles to be ordered' is the definition.
I can't judge whether this defines the answer.
'candles to be ordered' is the wordplay.
'to be ordered' indicates anagramming the letters.
'candles' anagrammed gives 'CALENDS'.
Can you help me to learn more?
(Other definitions for calends that I've seen before include "Start of Roman months" , "First day of month, in Rome" , "beginning of month" , "First of month (Roman)" .)
