Latin hymn describing the Last Judgement whose title translates as 'day of wrath' (4,4)

I believe the answer is:

dies irae

(Other definitions for dies irae that I've seen before include "section of Requiem?" , "when the Lord passes judgment?" , "Latin hymn (day of wrath)" , "Hymn featuring in a Requiem Mass" .)

I've seen this clue in The Mirror.
