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

(211) So make no haste against them; We only count out to them a (limited) number (of the days of the life of this world and delay their term so that they may increase in evil and sins).

(212) The day We shall gather the Muttaqun (the pious - See V.2:2) unto the Most Gracious (Allah), like a delegation (presented before a king for honour).

(213) And everyone of them will come to Him alone on the day of Resurrection (without any helper, or protector or defender).

(214) "Therefore, let not the one who believes not therein (i.e. in the day of Resurrection, Reckoning, Paradise and Hell.), but follows his own lusts, divert you therefrom, lest you perish.

(215) [Musa (Moses)] said: "Your appointed meeting is the day of the festival, and let the people assemble when the sun has risen (forenoon)."

(216) "So devise your plot, and then assemble in line. And whoever overcomes this day will be indeed successful."

(217) Whoever turns away from it (this Qur'an - i.e. does not believe in it, nor acts on its orders), verily, they will bear a heavy burden (of sins) on the day of Resurrection,

(218) They will abide in that (state in the Fire of Hell) - and evil indeed will it be that load for them on the day of Resurrection;

(219) The day when the Trumpet will be blown (the second blowing): that day, We shall gather the Mujrimun (criminals, polytheists, sinners, disbelievers in the Oneness of Allah) blue or blind-eyed with thirst.

(220) They will speak in a very low voice to each other (saying): "You stayed not longer than ten (days)."
