Aside from its historical implications and influences on other religious celebrations that occur during springtime, Beltane is important to those who celebrate for the same reasons any other religious holiday is important for any faith: It's a time to honor what you believe in. In the case of Beltane specifically, it's a time to celebrate fertility, the promise of new life, and the prospect of the warmth and light of the summer season, as well as the balance of the divine feminine and masculine.
