The word(s) "day" appears 704 time(s) in 579 verse(s) in Quran in Mohsin Khan translation.

(81) And on the day when We shall gather them all together, then We shall say to those who joined partners (in worship with Us): "Where are your partners (false deities) whom you used to assert (as partners in worship with Allah)?"

(82) And they said: "There is no (other life) but our (present) life of this world, and never shall we be resurrected (on the day of Resurrection)."

(83) Say: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?"

(84) It is He Who takes your souls by night (when you are asleep), and has knowledge of all that you have done by day, then He raises (wakes) you up again that a term appointed (your life period) be fulfilled, then (in the end) unto Him will be your return. Then He will inform you of that which you used to do.

(85) It is He Who has created the heavens and the earth in truth, and on the day (i.e. the day of Resurrection) He will say: "Be!", - and it is! His Word is the Truth. His will be the dominion on the day when the Trumpet will be blown. All-Knower of the unseen and the seen. He is the All-Wise, Well-Aware (of all things).

(86) And who can be more unjust than he who invents a lie against Allah, or says: "A revelation has come to me" whereas no revelation has come to him in anything ; and who says, "I will reveal the like of what Allah has revealed." And if you could but see when the Zalimun (polytheists and wrong-doers) are in the agonies of death, while the angels are stretching forth their hands (saying): "Deliver your souls! This day you shall be recompensed with the torment of degradation because of what you used to utter against Allah other than the truth. And you used to reject His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) with disrespect! "

(87) (He is the) Cleaver of the daybreak. He has appointed the night for resting, and the sun and the moon for reckoning. Such is the measuring of the All-Mighty, the All-Knowing.

(88) And on the day when He will gather them (all) together (and say): "O you assembly of jinn! Many did you mislead of men," and their Auliya' (friends and helpers) amongst men will say: "Our Lord! We benefited one from the other, but now we have reached our appointed term which You did appoint for us." He will say: "The Fire be your dwelling-place, you will dwell therein forever, except as Allah may will. Certainly your Lord is All-Wise, All-Knowing."

(89) O you assembly of jinn and mankind! "Did not there come to you Messengers from amongst you, reciting unto you My Verses and warning you of the meeting of this day of yours?" They will say: "We bear witness against ourselves." It was the life of this world that deceived them. And they will bear witness against themselves that they were disbelievers.

(90) And it is He Who produces gardens trellised and untrellised, and date-palms, and crops of different shape and taste (their fruits and their seeds) and olives, and pomegranates, similar (in kind) and different (in taste). Eat of their fruit when they ripen, but pay the due thereof (its Zakat according to Allah's Orders 1/10th or 1/20th) on the day of its harvest, and waste not by extravagance . Verily, He likes not Al-Musrifun (those who waste by extravagance),
