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

(161) (Remember) the day when We will call every people with their Imam; then whoever is given his book in his right hand, these shall read their book; and they shall not be dealt with a whit unjustly.

(162) And whomsoever Allah guides, he is the follower of the right way, and whomsoever He causes to err, you shall not find for him guardians besides Him; and We will gather them together on the day of resurrection on their faces, blind and dumb and deaf; their abode is hell; whenever it becomes allayed We will add to their burning.

(163) And thus did We rouse them that they might question each other. A speaker among them said: How long have you tarried? They said: We have tarried for a day or a part of a day. (Others) said: Your Lord knows best how long you have tarried. Now send one of you with this silver (coin) of yours to the city, then let him see which of them has purest food, so let him bring you provision from it, and let him behave with gentleness, and by no means make your case known to any one:

(164) And the day on which We will cause the mountains to pass away and you will see the earth a levelled plain and We will gather them and leave not any one of them behind.

(165) And on the day when He shall say: Call on those whom you considered to be My associates. So they shall call on them, but they shall not answer them, and We will cause a separation between them.

(166) And on that day We will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together;

(167) And We will bring forth hell, exposed to view, on that day before the unbelievers.

(168) These are they who disbelieve in the communications of their Lord and His meeting, so their deeds become null, and therefore We will not set up a balance for them on the day of resurrection.

(169) And peace on him on the day he was born, and on the day he dies, and on the day he is raised to life

(170) So eat and drink and refresh the eye. Then if you see any mortal, say: Surely I have vowed a fast to the Beneficent Allah, so I shall not speak to any man today.
