More About year
Long ago, people looked at the Sun and stars. They saw how the Earth moves. They made a year to count time. Now, we have a calendar to help us.
In our daily lives, we use a year to plan. We know when to go to school and when to have fun. It helps us remember special days.
In the future, we will still count years. Each year will still have seasons and days. We will keep using calendars to know what day it is.
