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

(411) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).

(412) And gave them clear proofs in matters [by revealing to them the Taurat (Torah)]. And they differed not until after the knowledge came to them, through envy among themselves. Verily, Your Lord will judge between them on the day of Resurrection about that wherein they used to differ.

(413) Say (to them): "Allah gives you life, then causes you to die, then He will assemble you on the day of Resurrection about which there is no doubt. But most of mankind know not."

(414) And to Allah belongs the kingdom of the heavens and the earth. And on the day that the Hour will be established - on that day the followers of falsehood (polytheists, disbelievers, worshippers of false deities) shall lose (everything).

(415) And you will see each nation humbled to their knees (kneeling): each nation will be called to its Record (of deeds). This day you shall be recompensed for what you used to do.

(416) And it will be said: "This day We will forget you as you forgot the Meeting of this day of yours. And your abode is the Fire, and there is none to help you."

(417) This, because you took the revelations of Allah (this Qur'an) in mockery, and the life of the world deceived you. So this day, they shall not be taken out from there (Hell), nor shall they be returned to the worldly life, (so that they repent to Allah, and beg His Pardon for their sins).

(418) And who is more astray than one who calls on (invokes) besides Allah, such as will not answer him till the day of Resurrection, and who are (even) unaware of their calls (invocations) to them?

(419) And when mankind are gathered (on the day of Resurrection), they (false deities) will become their enemies and will deny their worshipping.

(420) On the day when those who disbelieve (in the Oneness of Allah - Islamic Monotheism) will be exposed to the Fire (it will be said): "You received your good things in the life of the world, and you took your pleasure therein. Now this day you shall be recompensed with a torment of humiliation, because you were arrogant in the land without a right, and because you used to rebel against Allah's Command (disobey Allah).
