American Touch Tag Day is observed on October 08, 2017. Touch Tag is a playground game that involves one or more players chasing other players in an attempt to "tag" or touch them, usually with their hand. There are many variations; most forms have no teams, scores, or equipment.
A group of players decide who is going to be "it", often using a counting-out game such as eeny, meeny, miny, moe. The player selected to be "it" then chases the others, attempting to get close enough to tag them - touching them with a hand - while the others try to escape. A tag makes the tagged player "it" - in some variations, the previous "it" is no longer "it" and the game can continue indefinitely, while in others, both players remain "it" and the game ends when all players have become "it".
Tag and other chasing games have been banned in some schools in the United States and United Kingdom due to concerns about injuries and complaints from children of harassment. A principal who banned tag in their school criticized the game for creating a "self-esteem issue" in nominating one child as a victim, and noted that the oldest and biggest children usually dominated the game.
