At the end of the day is an idiom with several meanings. It can literally be the end of one’s waking hours, or the end of one’s work hours. The phrase can also be used in a summary statement to mean ‘when all the information has been considered’ or ‘the most important part is’.
A related phrase by the end of the day carries more of a deadline, but still can mean either the end of the work day or the end of one’s waking hours. This phrase is also used without the deadline to talk of a future time at which all the information would be considered.
