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

(361) So worship what you like besides Him. Say (O Muhammad صلى الله عليه وسلم): "The losers are those who will lose themselves and their families on the day of Resurrection. Verily, that will be a manifest loss!"

(362) Is he then, who will confront with his face the awful torment on the day of Resurrection (as he who enters peacefully in Paradise)? And it will be said to the Zalimun (polytheists and wrong-doers): "Taste what you used to earn!"

(363) Then, on the day of Resurrection, you will be disputing before your Lord.

(364) And those who did wrong (the polytheists and disbelievers in the Oneness of Allah), if they had all that is in earth and therewith as much again, they verily, would offer it to ransom themselves therewith on the day of Resurrection from the evil torment; and there will become apparent to them from Allah what they had not been reckoning.

(365) And on the day of Resurrection you will see those who lied against Allah (i.e. attributed to Him sons, partners) - their faces will be black. Is there not in Hell an abode for the arrogant?

(366) They made not a just estimate of Allah such as is due to Him. And on the day of Resurrection the whole of the earth will be grasped by His Hand and the heavens will be rolled up in His Right Hand.Glorified be He, and High be He above all that they associate as partners with Him!

(367) And those who disbelieved will be driven to Hell in groups till, when they reach it, the gates thereof will be opened (suddenly like a prison at the arrival of the prisoners). And its keepers will say, "Did not the Messengers come to you from yourselves, reciting to you the Verses of your Lord, and warning you of the Meeting of this day of yours?" They will say: "Yes, but the Word of torment has been justified against the disbelievers!"

(368) "And save them from (the punishment, for what they did of) the sins, and whomsoever You save from (the punishment for what he did of) the sins (i.e. pardon him) that day, him verily, You have taken into mercy." And that is the supreme success.

(369) (He is Allah) Owner of High Ranks and Degrees, the Owner of the Throne. He sends the revelation by His Command to any of His slaves He wills, that he (the person who receives revelation) may warn (men) of the day of Mutual Meeting (i.e. the day of Resurrection).

(370) The day when they will (all) come out, nothing of them will be hidden from Allah. Whose is the kingdom this day? (Allah Himself will reply to His Question): It is Allah's the One, the Irresistible!
