Time of year a beehive might be unmanageable? (3,4,3)
I believe the answer is:
bad hair day
'time' is the definition.
(I have seen 'awful time' mean 'bad hair day' so perhaps 'time' could also mean 'bad hair day')
'year a beehive might be unmanageable?' is the wordplay.
I cannot quite see how this works, but
'year' could be 'ad' (AD is an example) and 'ad' is found within the answer.
'a' is within the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bad hair day that I've seen before include "when mishaps occur" , "When everything seems to go wrong at the same time?" , "Time when things go wrong" , "When everything goes wrong (with one's locks?)" , "Having dodgy locks" .)
