复活节是一个西方的重要节日，在每年春分月圆之后第一个星期日。基督徒认为，复活节象征着重生与希望，为纪念耶稣基督于公元30到33年之间被钉死在十字架之后第三天复活的日子。日期年年不同，一般在3月22日至4月25日之间。
复活节最典型的传统习惯是复活节彩蛋。古人常把蛋视为多子多孙和复活的象征。后来基督教徒又认为它是耶稣墓的象征，未来的生命就是从其中挣脱而出世的。复活节时人们把鸡蛋染成红色，代表耶稣受难时流出的鲜血，同时也象征复活后的快乐。还有一种古老的习俗，是把煮熟的鸡蛋送给街头的孩子们做游戏，他们把蛋往前滚，谁的蛋最后破，谁就获得胜利，蛋全归他所有。兔子也是复活节的象征。因为兔子繁殖力很强，所以人们把它视为新生命的表现者。大人常绘声绘色地告诉孩子复活节彩蛋是兔子下的，并把彩蛋放在花园里，让孩子们玩找蛋游戏。 现在每逢复活节，美国大小糖果店总要出售用巧克力制成的复活节小兔和彩蛋。这些彩蛋小的和鸡蛋差不多，大的竟有甜瓜那么大，孩子们自然喜欢，送给亲戚朋友，也不失为上佳礼品。
