Question: I find it confusing when *tomorrow* is used to speak of a day in the future other than the following day. Is it proper to use it in reference to any specific day in the future?

I am aware that the dictionary defines tomorrow as a time in near future. To me this refers to an ambiguous time and it is not confusing when used as such. But, is it proper to use it of any specific day in the future other than the day after tomorrow. 

Ex. "We are going to the park tomorrow." Based on the dictionary definition, a student is using tomorrow to refer to a different day in the coming week. Am I wrong to correct this?

Is there a reputable source that confines the near future use of this word to metaphorical ambiguous future.

Answer: 
If you check with [a dictionary](http://oxforddictionaries.com/definition/english/tomorrow?q=tomorrow) you would realize

@Sarah I don't think so. If tomorrow can be used to specify a particular day in the future besides the day after today, by merely looking at the word "*tomorrow*", it is impossible for one to tell which particular day it refers to in the future. There are infinite possibilities (Let n be the value that represents today's date, x be a positive integer, n+x can represent an infinite set of values) and it makes no sense to me.
Many dictionaries (like [Collins](http://www.collinsdictionary.com/dictionary/english/tomorrow) and [Macmillan](http://www.macmillandictionary.com/dictionary/american/tomorrow_9)) list a secondary meaning for tomorrow, but that meaning is in an abstract sense, as in:

> 
> *Today's graduates are the leaders of tomorrow.*
> 
> 
> 

The word either expresses the day after today, or else a vague sense of sometime in the future. If today was Friday, I would **not** use *tomorrow* to refer to next Tuesday; if today is a day in March, I would not use *tomorrow* to refer to a specific date this summer. I don't think that's the way the word should be used, even when you're using the word as a substitute for *the future*.

If my daughter was already engaged, I would not say "She'll be married tomorrow" – not unless it was the day before her wedding. I suppose, though, if my daughter was in kindergarten, I might say, "She'll be married tomorrow" as a way of saying that she'll only be young for a finite amount of time, but I think even that is a stretch. I'd be better off saying something like, "She'll be married before we know it."
