Will Today word change the sentence tense? [closed]

Solution 1:

'Today' is quite a long time in some contexts so present, future, past simple and past perfect tenses can all be combined with the word "today" For example:

If you are speaking during a break in your class you can say "I am in class today".

If you're speaking before your class begins, you can say "I will be in class today".

If you're speaking when you are no longer in class you can say "I was in class today"

If you went to the bowling alley between the end of class and when you were speaking you could also say "I had been in class today before I went to the bowling alley." (although this is much less common).

There are some other valid uses of some of these tenses combined with the word 'today' but I believe that listing them would make this answer too complex.

The examples you have been given are just to make the difference between the present and past tenses clear. They don't mean that 'today' can only be used with the present tense.
