A day is considered from 12am on day to 12am the next day. What they are asking you to do is 100% legal and easily do-able from your vantage point. You can ask your manager that you prefer to not come in before noon when you have to work late the night before or try to trade shifts with someone if you really have a problem with it.
FYI: Doctors often work 30 hours shifts at least once or twice a week... yup, that's 30 hours straight, no sleep. Those short little shifts you are doing is nothing.
