The word(s) "day" appears 569 time(s) in 514 verse(s) in Quran in Abdullah Yusuf Ali translation.

(351) But is the (Unbelievers) are arrogant, (no matter): for in the presence of thy Lord are those who celebrate His praises by night and by day. And they never flag (nor feel themselves above it).

(352) Those who pervert the Truth in Our Signs are not hidden from Us. Which is better?- he that is cast into the Fire, or he that comes safe through, on the day of Judgment? Do what ye will: verily He seeth (clearly) all that ye do.
