April 25 has been chosen as Parental Alienation Awareness Day (PAAD), part of a global awareness campaign to raise awareness about parental alienation. The idea was introduced in Canada by Sarvy Emo in late 2005, with the original date being March 28. This date was changed after the start of the campaign to coincide with the appearance in Toronto of parental alienation expert Dr. Richard Warshak.
In 2011, Bermuda, Seventeen U.S. states (New York, Maine, Connecticut, Florida, Indiana, Iowa, Kentucky, Montana, Nebraska, Alabama, Arkansas, Georgia, Maryland, Mississippi, West Virginia, Indiana, Oklahoma), many Canadian towns and cities officially recognized April 25 as Parental Alienation Awareness Day. The day has since been arranged in 25 countries.
