The "Days of the Month" refer to the specific days that make up each month in the Gregorian calendar, which is the most widely used calendar system today. Each month has a varying number of days, ranging from 28 to 31. For example, February typically has 28 days, while January and March each have 31 days. Months are divided into four seasons: spring, summer, autumn, and winter. The total number of days in a year is usually 365, but during a leap year, which occurs every four years, February has 29 days, bringing the total to 366 days.
