Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh. 
It is permissible for spouses to engage in conjugal relationships at any time of the month including the beginning, middle and the end of the month with the obvious condition that the wife is not in her menses. Imam Ghazali (Rahimahullah) has stated that it is makrooh (disliked) to engage in conjugal relationships in the beginning, middle and end of the month and his view is based on the advises of some Sahabah. [1] While it is permissible for spouses to engage in conjugal relationship in the above mentioned days, one may also follow the advice of Imam Ghazali (Rahimahullah) if one wishes.
As for recommended days, Imaam Ghazali (Rahimahullah) mentions that Friday (which according to the Islamic calendar starts from Thursday maghrib) is preferred. [2]
