Diurnalpla

Diurnalpla is a term for those who feel that their platonic attraction is stronger during the day and weakens during the night, or simply doesn't exist at night. They may feel that the later it gets the more their platonic attraction weakens, or it may weaken an equal amount no matter the time of night.

The opposite is nocturnalpla.

The sexual counterpart is diurnalsexual, and the romantic counterpart is diurnalromantic.
