The Years
The years are units of time measuring how long it takes for the Earth to orbit the Sun once. A year, typically 365 days, helps us organize history, seasons, and life cycles. Every four years, we add an extra day in February (leap year) to keep calendars aligned with Earth's orbit. The concept of years allows us to track events, commemorate milestones, and understand the passage of time in a structured way. Over centuries, this measurement has helped civilizations record history, plan agriculture, and develop calendars for daily life.
