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

(381) The day when their excuses will be of no profit to Zalimun (polytheists, wrong-doers and disbelievers in the Oneness of Allah). Theirs will be the curse, and theirs will be the evil abode (i.e. painful torment in Hell-fire).

(382) Verily, the Hour (day of Judgement) is surely coming, there is no doubt about it, yet most men believe not.

(383) Allah, it is He Who has made the night for you that you may rest therein and the day for you to see. Truly, Allah is full of Bounty to mankind; yet, most of mankind give no thanks.

(384) Say (O Muhammad صلى الله عليه وسلم): "Do you verily disbelieve in Him Who created the earth in two days? And you set up rivals (in worship) with Him? That is the Lord of the 'Alamin (mankind, jinn and all that exists).

(385) He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four days equal (i.e. all these four days were equal in the length of time) for all those who ask (about its creation).

(386) Then He completed and finished from their creation (as) seven heavens in two days and He made in each heaven its affair. And We adorned the nearest (lowest) heaven with lamps (stars) to be an adornment as well as to guard (from the devils by using them as missiles against the devils). Such is the Decree of Him the All-Mighty, the All-Knower.

(387) So We sent upon them a furious wind in days of evil omen (for them) that We might give them a taste of disgracing torment in this present worldly life. But surely the torment of the Hereafter will be more disgracing, and they will never be helped.

(388) And (remember) the day that the enemies of Allah will be gathered to the Fire, then they will be driven [(to the Fire), former ones being withheld till their later ones will join them].

(389) And that thought of yours which you thought about your Lord, has brought you to destruction; and you have become (this day) of those utterly lost!

(390) And from among His Signs are the night and the day, and the sun and the moon. Prostrate yourselves not to the sun nor to the moon, but prostrate yourselves to Allah Who created them, if you (really) worship Him.
