Particular days for fruit (5)
I believe the answer is:
dates
This might be a double definition.
'particular days' is the first definition.
'dates' can be an answer for 'days' (date is a kind of day). I am unsure of the 'particular' bit.
'for fruit' is the second definition.
(type of fruit)
Can you help me to learn more?
(Other definitions for dates that I've seen before include "becomes less fresh" , "Particular times" , "Is seeing" , "Fruits for social engagements" , "Fruit - shows its age" .)
