There is an expression "all the day long", but it's unusual, maybe archaic.
Otherwise "all the day" is nearly impossible.
"The" creeps in only when something follows:
The baby was sleeping all the day that I visited her parents.
It snowed all the month of December.
I lived in China all the year 1984.
These sentences are possible, by I'm not sure all native speakers would accept them.
Otherwise, "all the day", etc., sound bad to me.
I don't know why, but "all day" and "all morning" and "all afternoon" and "all night" and "all year", are perfectly good English; "all week" is okay, but probably not as common, and I wouldn't say "all month" at all.
It puzzles me that Longman would give such strange advice.

As an ESL learner, how should we use these phrases? Thank you.
Thank you very much for your help. And I must tell you that it was I, not Longman, who was mistaken. LONGMAN ENGLISH GRAMMAR, 5.22.2 says:
"All' can be used in: all (the) day/ night/ week/ year/ summer, but not with hour/ century. (I'm using LONGMAN'S Chinese translation, not the original grammar. So my sentence here is not its original description.)
I REALLY must apoligize to L.G. Alexander for this serious mistake. LONGMAN GRAMMAR is my favourite grammar book. And the word 'month' is not included in all these phrases.
