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

(171) (And it will be said unto him): Read thy Book. Thy soul sufficeth as reckoner against thee this day.

(172) A day when He will call you and ye will answer with His praise, and ye will think that ye have tarried but a little while.

(173) There is not a township but We shall destroy it ere the day of Resurrection, or punish it with dire punishment. That is set forth in the Book (of Our decrees).

(174) He said: Seest Thou this (creature) whom Thou hast honoured above me, if Thou give me grace until the day of Resurrection I verily will seize his seed, save but a few.

(175) On the day when We shall summon all men with their record, whoso is given his book in his right hand - such will read their book and they will not be wronged a shred.

(176) And he whom Allah guideth, he is led aright; while, as for him whom He sendeth astray, for them thou wilt find no protecting friends beside Him, and We shall assemble them on the day of Resurrection on their faces, blind, dumb and deaf; their habitation will be hell; whenever it abateth, We increase the flame for them.

(177) And in like manner We awakened them that they might question one another. A speaker from among them said: How long have ye tarried? They said: We have tarried a day or some part of a day, (Others) said: Your Lord best knoweth what ye have tarried. Now send one of you with this your silver coin unto the city, and let him see what food is purest there and bring you a supply thereof. Let him be courteous and let no man know of you.

(178) And (bethink you of) the day when we remove the hills and ye see the earth emerging, and We gather them together so as to leave not one of them behind.

(179) And (be mindful of) the day when He will say: Call those partners of Mine whom ye pretended. Then they will cry unto them, but they will not hear their prayer, and We shall set a gulf of doom between them.

(180) And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering.
