Definition: A "common year" is a noun that refers to a year that is not a leap year. In a common year, there are 365 days. This is different from a leap year, which has 366 days because an extra day is added to February (February 29).
In more advanced contexts, you might encounter discussions about the Gregorian calendar, where "common year" is used to explain the structure of the calendar system. For example: - "According to the Gregorian calendar, a common year occurs every year that is not divisible by 4, except for years that are divisible by 100 unless they are also divisible by 400."
In English, "common" can also mean something that is ordinary or usual. However, in this context, it specifically refers to a type of year in the calendar.
There are no direct synonyms for "common year," but you can use phrases like "regular year" or "standard year" to convey a similar meaning in some contexts.
There are no specific idioms or phrasal verbs directly related to "common year." However, it can be discussed in phrases related to time, such as: - "Time flies" – meaning that time seems to pass quickly, which can apply to any year, common or leap.
A common year is simply a regular year with 365 days, in contrast to a leap year which has 366 days.
