The word(s) "day" appears 533 time(s) in 482 verse(s) in Quran in Muhammad Habib Shakir translation.

(341) And Allah's is the kingdom of the heavens and the earth; and on the day when the hour shall come to pass, on that day shall they perish who say false things.

(342) And you shall see every nation kneeling down; every nation shall be called to its book: today you shall be rewarded for what you did.

(343) And it shall be said: Today We forsake you as you neglected the meeting of this day of yours and your abode is the fire, and there are not for you any helpers:

(344) That is because you took the communications of Allah for a jest and the life of this world deceived you. So on that day they shall not be brought forth from it, nor shall they be granted goodwill.

(345) And who is in greater error than he who calls besides Allah upon those that will not answer him till the day of resurrection and they are heedless of their call?

(346) And on the day when those who disbelieve shall be brought before the fire: You did away with your good things in your life of the world and you enjoyed them for a while, so today you shall be rewarded with the punishment of abasement because you were unjustly proud in the land and because you transgressed.

(347) And mention the brother of Ad; when he warned his people in the sandy plains,-- and indeed warners came before him and after him-- saying Serve none but Allah; surely I fear for you the punishment of a grievous day.

(348) And on the day when those who disbelieve shall be brought before the fire: Is it not true? They shall say: Aye! by our Lord! He will say: Then taste the punishment, because you disbelieved.

(349) Therefore bear up patiently as did the apostles endowed with constancy bear up with patience and do not seek to hasten for them (their doom). On the day that they shall see what they are promised they shall be as if they had not tarried save an hour of the day. A sufficient exposition! Shall then any be destroyed save the transgressing people?

(350) When those who disbelieved harbored in their hearts (feelings of) disdain, the disdain of (the days of) ignorance, but Allah sent down His tranquillity on His Apostle and on the believers, and made them keep the word of guarding (against evil), and they were entitled to it and worthy of it; and Allah is Cognizant of all things.
