The first day of Christmas starts on December 25th and lasts until January 5th. It is a season of giving, joy, and peace, and is celebrated by Christians around the world as the birth of Jesus Christ. During this time, people exchange gifts, spend time with loved ones, and participate in various traditions such as caroling, baking, and decorating. It is also a time of reflection, as many people use this time to show gratitude for their blessings and focus on being kind and generous to others.
