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

(201) And on that day [i.e. the day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another; and the Trumpet will be blown, and We shall collect them (the creatures) all together.

(202) And on that day We shall present Hell to the disbelievers, plain to view -

(203) "They are those who deny the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord and the Meeting with Him (in the Hereafter). So their works are in vain, and on the day of Resurrection, We shall assign no weight for them.

(204) And Salam (peace) be on him the day he was born, and the day he dies, and the day he will be raised up to life (again)!

(205) "So eat and drink and be glad. And if you see any human being, say: 'Verily! I have vowed a fast unto the Most Gracious (Allah) so I shall not speak to any human being this day.'"

(206) "And Salam (peace) be upon me the day I was born, and the day I die, and the day I shall be raised alive!"

(207) Then the sects differed [i.e. the Christians about 'Îsa (Jesus) عليه السلام], so woe unto the disbelievers [those who gave false witness by saying that 'Îsa (Jesus) is the son of Allah] from the Meeting of a great day (i.e. the day of Resurrection, when they will be thrown in the blazing Fire) .

(208) How clearly will they (polytheists and disbelievers in the Oneness of Allah) see and hear the day when they will appear before Us! But the Zalimun (polytheists and wrong-doers) today are in plain error.

(209) And warn them (O Muhammad صلى الله عليه وسلم) of the day of grief and regrets, when the case has been decided, while (now) they are in a state of carelessness, and they believe not .

(210) Nay, but they (the so-called gods) will deny their worship of them, and become opponents to them (on the day of Resurrection).
