'time for continental celebration' is the definition.
I can't judge whether this defines the answer.

'a busy month could somehow' is the wordplay.
'month' becomes 'M' (standard abbreviation).
'somehow' indicates anagramming the letters.
'a'+'busy'+'m'+'could'='abusymcould'
'abusymcould' anagrammed gives 'COLUMBUS DAY'.

'become' acts as a link.

Can you help me to learn more?
