Morphology
The meaning refers to a specific South Korean cultural observance (singles eating jajangmyeon on April 14) that cannot be deduced from the literal words 'black' and 'day'. A B1 learner who knows the constituents would not predict the singles' ritual or the noodle dish; the sense is culturally specific and therefore not compositional.
Etymology
Black day in Korea is a modern name for April 14 when single people eat black-bean noodles called jajangmyeon; the dark noodles (the color black) gave the day its name, and eating them became a way to mark 'being single'.
