How long should you wait until a guy sets a plan for a date?

Heyyy

So we met on Hinge and he seemed very interested.

On Saturday we started talking about meeting sometime soon.

Might put in the exact time line xD:

1. Late on Saturday evening I suggested that we could meet on either Monday or Tuesday.

At about 11pm he agreed on Tuesday and asked what I fancied on doing.

2 . Next morning (which was Sunday). I replied that "maybe we could grab a bite?".

I sent that early on Sunday morning.

Today is Monday already and there's still no reply from him.

We are supposed to meet tomorrow. How long should I wait for him to confirm that he's ok with getting food before planning on doing something else tomorrow?

He said Mondays are busy for him but I haven't received a reply a whole day yesterday and don't think it would take that long to set a quick plan if a guy wants to meet you?

Am I being ghosted here? xD

FYI, I'm 31, he's 4 years older.
