Is that Jack Lord?  Or Del Lord?  Or Marjorie Lord?  These Rateitall questions have to be more specific.  If it's the first, the answer would be "Any day that McGarrett wasn't on duty at Hawaii 5-0."  If it's the second, it was anytime he wasn't at call down at the movie studio, because The Three Stooges were on vacation.  If it's the third, it was anytime she wan't making room for daddy.

Judgment Day. Totally different from a 24 hour day, since it will take place in Heaven, and no one will be alive as we are now.

Why can't God's Day be today, since He has made all things? Why can't it be tomorrow, and the next day, and so on? :)

The Day of the Lord is by no means a picnic. Check and read these Scriptures: Obadiah 1:5- Amos 5:18- Joel 2:1- Ezekiel 30:3- Isaiah 2:12- 13:9- 24:21- 34:8..Now, you tell me do these sound wonderful?, If you get left behind, you will face this head on, get saved today, trust the Gospel (1Corinthians 15:1-4) God bless you.

The great and terrible Day. His Day. Great for those who love Him, terrible for those who don't. Don't misunderstand me. Many people who don't believe on Him at this time will at that time. How can you love someone you don't even know? He's not angry with anyone who simply doesn't know Him, but, once they do and still reject Him, well... they can float their own boat. The Day of The Lord is when all will be told the truth.

Some people actually believe that this means the Sabbath, because it was the day God made holy and they use the fact that in Revelation, John's experience happened on the Day of the Lord. They use this as a strong case as to why we should still be observing the Sabbath. But the Day of the Lord actually means the day that Jesus will return to this earth and call the righteous to salvation, and the guilty to judgement.
