The answer to the brain teaser "What is the day before today if two days from now will be the second day this week that will be hotter than today" is Friday.

If you capitalize the first letter of the sentence and place a period at the end, use an apostrophe for the contraction for 'it's', it is a correct sentence: It's going to be a great night today. Although correct as a sentence, it would make more sense if it said: It's going to be a great night tonight.
