There are many synonyms for the term "regular years," including the most common one which is "common years." Other synonyms include "normal years," "ordinary years," or "non-leap years." These terms are used to refer to the years that do not have an extra day added to them, unlike leap years. In a regular year, there are 365 days, and the months are structured as they typically are. It's essential to differentiate between regular years and leap years as several yearly events depend on this distinction, such as the timing of the Olympic Games, presidential elections, and more. Overall, the synonyms for regular years remind us that these years are the standard ones we experience most of the time.
