No women around - it's heavenly (3,4)
I believe the answer is:
new moon
'it's heavenly' is the definition.
I can't tell whether this definition defines the answer.
'no women around' is the wordplay.
'around' indicates anagramming the letters.
'no'+'women'='nowomen'
'nowomen' is an anagram of 'NEW MOON'.
Can you help me to learn more?
(Other definitions for new moon that I've seen before include "Phase of Earth's satellite" , "Start of month for some" , "Earth's satellite when appearing as a narrow crescent" , "First phase(s) of lunar cycle" , "Beginning of first quarter" .)
