Christmas is a celebration held on the 25th of December to mark the anniversary of the birth of Jesus Christ. Christmas is typically celebrated by getting together with your family to share a meal and give gifts.
Easter is a celebration that happens once a year, on the first Sunday after the first full moon after the vernal equinox. Easter usually falls in March or April. Easter celebrates the resurrection of Jesus Christ, although modern familes who aren't practicing Christians will use the event to hold a hunt for chocolate or plain Easter eggs with their children.
Halloween is a celebration that takes place on October 31st. On Halloween, children go trick-or-treating, collecting sweets and candy around their neighbourhood. Both adults and children like to dress up in costumes of witches and ghosts, and people also carve Jack-o-lanterns out of pumpkins for Halloween.
