Halloween is celebrated by children and adults across the UK on the 31 October each year.
The day is marked by the carving of pumpkins into faces, then lighting them to let others know you are also supporting Halloween.
Halloween has been celebrated in the United Kingdom since the 19th Century and is celebrated on the eve of the Catholic festival of All Saints.

31 October - Check your local weather forecast if you are planning to celebrate Halloween.
Children mark the celebration of Halloween by dressing up in spooky costumes and visiting the homes of friends and relatives trick-or-treating. They will then receive sweet treats from each of the homes they visit if they offer a treat. Traditionally, if the home owner doesn't offer a treat, the children will play a small trick on the homeowner.
Trick-or-treaters will be hoping for a dry, clear night on Halloween so their pumpkins stay alight in their doorways.
