A year is a unit of time that helps us measure how long it takes for the Earth to complete one full orbit around the Sun. This journey takes about 365 days, which is why we have a year made up of months and days. Each year, we experience different seasons like spring, summer, autumn, and winter, which change the weather and the environment around us. In many cultures, a year is also a time for celebrations and traditions. For example, people celebrate the start of a new year on January 1st with fireworks and parties. Additionally, some cultures have their own unique new year celebrations, like the Chinese New Year, which is based on the lunar calendar.
