Is there a synonym for “day” that can go with “at night”, “at dusk”, “at dawn”? [closed]

I need a word (ideally) or phrase that means "daytime" that can be used in a sentence "the event happened at dawn/dusk/night/day"

"The event happened at day", and "The event happened at daytime" don't seem to really sound right.

The key thing here is fitting into a sentence that has the word 'at' in it, because it is going into construction of a sentence on a web site that has to cover these possibilities.

A typical example might be "The battle occurred at night in the rain", or "The battle occurred at day in the mist". The latter doesn't sound right.

I think that trying to avoid common colloquial usage would only confuse the reader.

"Most automobile accidents occur at night. Most people work during the day."

There is no normal-sounding at phrase, but you might try in daylight.
