Christmas vs. Eve — What's the Difference?

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration by billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night.

Eve (; Hebrew: חַוָּה‎, Chava /χaˈva/, Tiberian: Ḥawwāh; Arabic: حَوَّاء‎, romanized: Ḥawwāʾ; Greek: Εὕα, romanized: Heúa; Latin: Eva, Heva; Syriac: ܚܰܘܳܐ romanized: ḥawâ) is a figure in the Book of Genesis in the Hebrew Bible and the Quran. According to the origin story of the Abrahamic religions, she was the first woman, yet some debate within Judaism has also given that position to Lilith.
