The Fascinating World of Calendars

How we organize our days, months, and years

Introduction

A calendar is one of the oldest tools developed by humanity to measure time. From ancient civilizations to modern-day societies, calendars play a crucial role in organizing our lives. They allow us to plan events, keep track of time, and coordinate activities across the globe. Calendars are more than just tools—they reflect culture, religion, and advancements in science.
