Twelve-month calendar

A twelve-month calendar divides the year into 12 sections, typically ranging from 28 to 31 days each, representing the time Earth takes to orbit the Sun. It’s a standardized way to organize days, weeks, and months for tracking dates and planning activities. Most calendars are based on the Gregorian system, which ensures consistency across global systems, accounting for leap years every four years to keep the calendar aligned with Earth's orbit. Overall, it provides a structured framework to manage time efficiently through the year.
