The word(s) "days" appears 32 time(s) in 30 verse(s) in Quran in Muhammad Pickthal translation.

(21) Allah it is Who created the heavens and the earth, and that which is between them, in six days. Then He mounted the Throne. Ye have not, beside Him, a protecting friend or mediator. Will ye not then remember?

(22) Say (O Muhammad, unto the idolaters): Disbelieve ye verily in Him Who created the earth in two days, and ascribe ye unto Him rivals? He (and none else) is the Lord of the Worlds.

(23) He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four days, alike for (all) who ask;

(24) Then He ordained them seven heavens in two days and inspired in each heaven its mandate; and We decked the nether heaven with lamps, and rendered it inviolable. That is the measuring of the Mighty, the Knower.

(25) Therefor We let loose on them a raging wind in evil days, that We might make them taste the torment of disgrace in the life of the world. And verily the doom of the Hereafter will be more shameful, and they will not be helped.

(26) Tell those who believe to forgive those who hope not for the days of Allah; in order that He may requite folk what they used to earn.

(27) And verily We created the heavens and the earth, and all that is between them, in six days, and naught of weariness touched Us.

(28) He it is Who created the heavens and the earth in six days; then He mounted the Throne. He knoweth all that entereth the earth and all that emergeth therefrom and all that cometh down from the sky and all that ascendeth therein; and He is with you wheresoever ye may be. And Allah is Seer of what ye do.

(29) Which He imposed on them for seven long nights and eight long days so that thou mightest have seen men lying overthrown, as they were hollow trunks of palm-trees.

(30) (And it will be said unto those therein): Eat and drink at ease for that which ye sent on before you in past days.
