The word(s) "day" appears 533 time(s) in 482 verse(s) in Quran in Muhammad Habib Shakir translation.

(181) Whoever turns aside from it, he shall surely bear a burden on the day of resurrection

(182) Abiding in this (state), and evil will it be for them to bear on the day of resurrection;

(183) On the day when the trumpet shall be blown, and We will gather the guilty, blue-eyed, on that day

(184) We know best what they say, when the fairest of them in course would say: You tarried but a day.

(185) On that day they shall follow the inviter, there is no crookedness in him, and the voices shall be low before the Beneficent Allah so that you shall not hear aught but a soft sound.

(186) On that day shall no intercession avail except of him whom the Beneficent Allah allows and whose word He is pleased with.

(187) And whoever turns away from My reminder, his shall be a straitened life, and We will raise him on the day of resurrection, blind.

(188) He will say: Even so, Our communications came to you but you neglected them; even thus shall you be forsaken this day.

(189) Bear then patiently what they say, and glorify your Lord by the praising of Him before the rising of the sun and before its setting, and during hours of the night do also glorify (Him) and during parts of the day, that you may be well pleased

(190) They glorify (Him) by night and day; they are never languid.
