Nine-to-five is a common expression used to describe a regular work day schedule, typically from 9am to 5pm. However, there are several other words and phrases that can be used to describe this same schedule. Some alternatives include "standard hours," "regular schedule," "office hours," "business hours," "working hours," or simply "full-time." Additionally, this phrase is often associated with a traditional office job, so synonyms that emphasize the professional nature of the job might be "white-collar," "corporate," or "desk job." Regardless of the wording used, these expressions all refer to the typical work schedule of an average weekday.
