Why do some people not celebrate holidays? Can I celebrate?
Here's the answer:

Some people choose not to celebrate holidays because of their own personal feelings. However, there is nothing wrong if you want to celebrate holidays.
Many holidays that we celebrate today are not mentioned in the Bible. These holidays include Christmas, Thanksgiving, Valentine’s Day, Easter, or New Year's. In fact, the only holidays mentioned in the Bible are Jewish feast days. These feasts are Passover (Mark 14:12), Unleavened Bread (Leviticus 23:6), Firstfruits (Leviticus 23:10; 1 Corinthians 15:20), Pentecost (Leviticus 23:15; Acts 2:1), Trumpets (Leviticus 23:24), the Day of Atonement (Leviticus 23:27), and Tabernacles (Leviticus 23:34).
Despite these feast days being listed in the Bible, we are not under obligation to observe them as Christians. Since Jesus is the fulfillment of the Jewish Law (Matthew 5:17), there is no reason for us to celebrate these feast days. Some Christians might choose to celebrate these days, and that is completely okay, but none of us are required to celebrate these holidays.
Christmas is a holiday that was created after the end of the New Testament, and it is the celebration of the Lord’s birth into the world. Easter was also created after the completion of the New Testament, and it is a celebration of the resurrection of the Lord. As believers, we can celebrate these holidays because they are ultimately celebrating the Lord. Some people might not want to observe these holidays because they were created after the Bible, but there is nothing wrong if you want to celebrate them each year.
Even for holidays such as Thanksgiving, St. Patrick's Day, or Valentine’s Day, you can celebrate them with a joyful heart. By connecting them back to biblical principles of thankfulness, joy, and love, you can bring glory to God through your celebrations. Whether a person celebrates a holiday or not is up to them; therefore, you can choose which holidays you are going to celebrate.
