【2020万圣节的由来英文版简短带中文】Halloween, or "All Hallows' Eve," is the night before All Saints' Day. It has its roots in ancient Celtic traditions. The Celts celebrated their new year on November 1st, and they believed that on the night before, the boundary between the living and the dead was thin. This time was called Samhain, a festival to honor the dead and protect against evil spirits.

In the 8th century, Pope Gregory IV moved the celebration of All Saints' Day to November 1st, making October 31st the eve of this holy day. Over time, the Christian holiday merged with the older pagan traditions, leading to the modern Halloween we know today.

Halloween is now widely celebrated around the world, especially in the United States. People dress up in costumes, go trick-or-treating, and carve pumpkins into jack-o'-lanterns. These customs have evolved from ancient beliefs and rituals, but they continue to bring joy and fun to people of all ages.

万圣节的由来（英文版简短带中文）

万圣节，即“万灵节前夜”，是万圣节（All Saints' Day）的前一天。它的起源可以追溯到古代凯尔特人的传统。凯尔特人将11月1日视为新年的开始，他们相信在这一天之前，生者与死者之间的界限变得模糊。这段时间被称为萨温节（Samhain），是一个纪念亡灵并抵御邪恶灵魂的节日。

公元8世纪，教皇格里高利四世将万圣节的庆祝活动移到了11月1日，使得10月31日成为这个神圣日子的前夜。随着时间的推移，基督教节日与古老的异教传统融合，形成了我们今天所知道的现代万圣节。

如今，万圣节在全球范围内广受欢迎，尤其是在美国。人们会穿上各种服装，进行“不给糖就捣蛋”的活动，并把南瓜雕刻成杰克灯（jack-o'-lantern）。这些习俗源于古代的信仰和仪式，但它们依然为各个年龄段的人们带来欢乐和乐趣。
