This site briefly kept a calendar containing details of puzzle events, open to the public, likely to be of particular interest to UK and Irish solvers. It includes in-person events within the UK and Ireland and selected online hunts where solvers’ locations are not so relevant. For a global view, you are recommended to view the Puzzle Hunt Calendar, the janko.at Puzzle Event Calendar and the Puzzle Place Calendar, to which acknowledgments are paid.

This calendar has not been updated since late 2015 and will no longer be updated.
