Learn English – Looking for a word for the point in time where one day becomes another

single-word-requests

I need help finding a good word for the point in time where one day switches to the next. Obviously, the actual point in time would be midnight, but I want a word to emphasize the fact that something is happening over the switching point between two days. So the word I'm looking for would be something like "day limit" or "daybreak", but neither of these sounds very good.

If any kind of digital clock or calendar is in the picture, then rollover can describe this.

It needs a little context to make it clear: e.g. something like “Nominations open Saturday February 21, at the rollover” may not be understood by all readers, but “Nominations open at midnight, on the rollover from Fri 20 to Sat 21” should be well understood, as should “Nominations open Friday night, at the rollover from 11:59 to 12:00”.
