Din klara sol går åter opp is a song with lyrics by Johan Olof Wallin, from 1814.
Being a Christian morning hymn about Sunrise, it was a common morning prayer song[1] in the Swedish primary school for decades.
Johan Georg Christian Störl is often credited as composer of the tune.
[2] The hymn is also sung during the school scenes in 1920 in the 2020 television series Mirakel.
In English, the hymn is called Again, Thy Glorious Sun Doth Rise.
