The word(s) "day" appears 568 time(s) in 513 verse(s) in Quran in Muhammad Pickthal translation.

(211) The Supreme Horror will not grieve them, and the angels will welcome them, (saying): This is your day which ye were promised;

(212) The day when We shall roll up the heavens as a recorder rolleth up a written scroll. As We began the first creation, We shall repeat it. (It is) a promise (binding) upon Us. Lo! We are to perform it.

(213) On the day when ye behold it, every nursing mother will forget her nursling and every pregnant one will be delivered of her burden, and thou (Muhammad) wilt see mankind as drunken, yet they will not be drunken, but the Doom of Allah will be strong (upon them).

(214) Turning away in pride to beguile (men) from the way of Allah. For him in this world is ignominy, and on the day of Resurrection We make him taste the doom of burning.

(215) Lo! those who believe (this revelation), and those who are Jews, and the Sabaeans and the Christians and the Magians and the idolaters - Lo! Allah will decide between them on the day of Resurrection. Lo! Allah is Witness over all things.

(216) That they may witness things that are of benefit to them, and mention the name of Allah on appointed days over the beast of cattle that He hath bestowed upon them. Then eat thereof and feed therewith the poor unfortunate.

(217) How many a township have We destroyed while it was sinful, so that it lieth (to this day) in ruins, and (how many) a deserted well and lofty tower!

(218) And they will bid thee hasten on the Doom, and Allah faileth not His promise, but lo! a day with Allah is as a thousand years of what ye reckon.

(219) And those who disbelieve will not cease to be in doubt thereof until the Hour come upon them unawares, or there come unto them the doom of a disastrous day.

(220) The Sovereignty on that day will be Allah's, He will judge between them. Then those who believed and did good works will be in Gardens of Delight,
