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

(231) Say: "Who can guard and protect you in the night or in the day from the (punishment of the) Most Gracious (Allah)?" Nay, but they turn away from the remembrance of their Lord.

(232) And We shall set up balances of justice on the day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We to take account.

(233) And the true promise (day of Resurrection) shall draw near (of fulfillment). Then (when mankind is resurrected from their graves), you shall see the eyes of the disbelievers fixedly staring in horror. (They will say): "Woe to us! We were indeed heedless of this - nay, but we were Zalimun (polytheists and wrong-doers)."

(234) The greatest terror (on the day of Resurrection) will not grieve them, and the angels will meet them, (with the greeting): "This is your day which you were promised."

(235) And (remember) the day when We shall roll up the heaven like a scroll rolled up for books. As We began the first creation, We shall repeat it. (It is) a promise binding upon Us. Truly, We shall do it.

(236) But if they (disbelievers, idolaters, Jews, Christians, polytheists) turn away (from Islamic Monotheism) say (to them O Muhammad صلى الله عليه وسلم): "I give you a notice (of war as) to be known to us all alike. And I know not whether that which you are promised (i.e. the torment or the day of Resurrection) is near or far. "

(237) The day you shall see it, every nursing mother will forget her nursling, and every pregnant one will drop her load, and you shall see mankind as in a drunken state, yet they will not be drunken, but severe will be the Torment of Allah.

(238) Bending his neck in pride (far astray from the Path of Allah), and leading (others) too (far) astray from the Path of Allah. For him there is disgrace in this worldly life, and on the day of Resurrection We shall make him taste the torment of burning (Fire).

(239) Verily, those who believe (in Allah and in His Messenger Muhammad صلى الله عليه وسلم), and those who are Jews, and the Sabians, and the Christians, and the Majus, and those who worship others besides Allah, truly, Allah will judge between them on the day of Resurrection. Verily! Allah is over all things a Witness.

(240) That they may witness things that are of benefit to them (i.e. reward of Hajj in the Hereafter, and also some worldly gain from trade), and mention the Name of Allah on appointed days (i.e. 10th, 11th, 12th, and 13th day of Dhul-Hijjah), over the beast of cattle that He has provided for them (for sacrifice), [at the time of their slaughtering by saying: (Bismillah, Wallahu-Akbar, Allahumma Minka wa Ilaik).] Then eat thereof and feed therewith the poor having a hard time.
