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

(531) (From) the Lord of the heavens and the earth, and whatsoever is in between them, the Most Gracious, with Whom they cannot dare to speak (on the day of Resurrection except by His Leave).

(535) On the day (when the first blowing of the Trumpet is blown), the earth and the mountains will shake violently (and everybody will die).

(536) (Some) hearts that day will shake with fear and anxiety.

(537) But when there comes the greatest catastrophe (i.e. the day of Recompense) -

(538) The day when man shall remember what he strove for.

(539) The day they see it, (it will be) as if they had not tarried (in this world) except an afternoon or a morning.

(540) Then when there comes As-Sakhkhah (the second blowing of the Trumpet on the day of Resurrection)
