Is there a word that means whether a thing happens at night or during the day?

Question

I know nocturnal means at night, could probably come with the word that means by day, but I need a word for that attribute of a thing - it s, what - diurnality?  something.  A word that means its "night or dayness of occurrence".  Anyone know how to say that?

I'm not sure whether "diurnality" is a word, but it would be clear to me what you meant if you used it something like this:

"The diurnality of the animal is uncertain."

But you could also use the known good word "diurnal" this way:

"Whether or not the animal is completely diurnal is uncertain."
