Suicide rate doubles during the holiday.

Hi.

The most difficult area of English to those whose native tongue is not English, is I'm pretty much sure, articles.

I watched the movie, 'The family man'. Part of the story.
On a Christmas morning, Jack, a very successful businessman, wakes up to realize his life turned into a big mess.
All he had - his money, his car, his building, is gone.
Trying to figure out what ever happened, he rushes to New York city where he worked and finds out something went terribly wrong.
Quite depressed, he returns home, and begins a conversation with his best buddy, Arnie.

ARNIE: You and me, buddy, we know how to live huh?. come on.
Come on, buddy. Take a seat. Are you okay?
I mean, you take off Christmas morning, you know,
you don’t tell anyone where you’regoin’.

JACK: We’re friends?

ARNIE: Talk to me.

JACK: I’m having kind of a bad day.

ARNIE: You know, I read somewhere that the suicide rate doubles during THE holiday.
What am I saying that for? You don’t wanna hear that. come on.

Arnie clearly mentioned 'during the holiday', and I wonder if 'the holiday' refers to the Christmas only, the very day Jack disappeared
or it includes all the other holidays, like, Thanksgiving Day, the Memorial Day or things like that.

I found this sentence while surfing the net.

The wolf is the largest member of the dog family.

Here, 'the wolf' refers to wolves in general, right?
Likewise, 'the holiday' can mean 'all the holidays', I guess.

Now let's get back to the sentence.

I read somewhere that the suicide rate doubles during THE holiday

From the native speaker's point of view,
what exactly does 'the holiday' refer to?
The Christmas only? Or it includes all the other holidays?

If Arnie had said, 'during holidays', I wouldn't have any doubt
thinking he meant all holidays by that.
Unfortunately though, he added 'the' and used singular form 'holiday', not 'holidays'.

I'm dying to know.
I'd appreciate it if you helped me, please.
