A month is a unit of time that typically consists of 28 to 31 days. It is part of the calendar system used to organize days, weeks, and years. The Gregorian calendar, which is the most widely used calendar today, has 12 months, including January, February, March, and so on. Each month has its own significance, often related to seasons, holidays, or cultural events. Months are used to track time for various purposes, such as scheduling events, planning activities, and managing finances. The concept of a month helps people understand the passage of time and organize their lives. For example, February usually has 28 days, except in leap years when it has 29 days.
