how can i prepare my synonyms and antonyms ?

Where was a very different atmosphere in the town this morning than yesterday.

I think some serious errors are committed by the worthy members to correct the sentence.
Pl note this is a statement not a question , therefore, it starts with 'It' not 'Where'.The correct version is

It was a very different atmosphere in the town this morning than that of yesterday.

Using Yesterday's is also incorrect as we don't use apostrophe 's with abstract nouns.

I think it should be ' One man's villain is another man's hero '.
