The word 'diurnal' is used to describe things that happen during the day or are active during the day, as opposed to things that happen at night or are active at night. For example, diurnal animals, such as birds and squirrels, are active during the day while nocturnal animals, like bats and owls, are active at night. Diurnal rhythms refer to the physical and behavioral changes in living organisms that occur over a 24-hour cycle. You may come across the word diurnal in scientific or technical contexts. In general conversation, it is not a common word.
