The spelling of the phrase "wrought day night" can be a bit confusing, but it can be broken down using IPA phonetic transcription. The first word, "wrought," is pronounced as /rɔːt/. It is spelled with the combination of letters "w-r-o-u-g-h-t" but is pronounced without the "g" sound. The second part, "day night," is pronounced as /deɪ naɪt/. It is spelled exactly as it sounds. Together, "wrought day night" is an old-fashioned expression that means working continuously, day and night.
