Why do we have months?

Months exist primarily as a means of organizing and measuring time, reflecting the lunar cycles that roughly divide the year into manageable segments. Historically, many cultures based their calendars on the moon's phases, leading to the creation of months to track seasonal changes and agricultural activities. Today, the Gregorian calendar, widely used around the world, standardizes months for civil purposes, facilitating scheduling and coordination in daily life. This system helps us structure our lives, from planning events to managing work and personal commitments.
