Usage
What does January mean? January is the first month of the calendar year. It has 31 days and is followed by February. It follows December, the twelfth and final month of the previous year. January is closely associated with its position at the beginning of the year. January 1 is known as New Year’s Day due to being the first day of the year. For many people, January is a time of making New Year’s resolutions—decisions to do something or make some change in the new year, especially to change or start some habit or behavior. For example, many people start new exercise routines or diets in January. In the Northern Hemisphere, January is a winter month. In the Southern Hemisphere, it is a summer month. In the U. S., the most notable holiday in January after New Year’s Day is Martin Luther King Day, which is observed on the third Monday of the month. The inaugurations of new U. S. presidents and members of Congress are also held in January. Example: People treat January as a time of new beginnings and life changes, but I like to remind them that they can do that during any month.
