A more thorough explanation:

Trinity sittings is a term used in English law. It refers to a period of time when courts are in session, starting on May 22 and ending on June 12 every year. This term was previously known as Trinity term until 1875.

For example, if a court case is scheduled for a hearing during the Trinity sittings, it means that the hearing will take place between May 22 and June 12.

Trinity sittings are one of four terms of court in the English legal system. The other three terms are Easter sittings, Hilary sittings, and Michaelmas sittings.

These terms help to organize the court system and ensure that cases are heard in a timely manner. They also provide a predictable schedule for lawyers, judges, and other court personnel.
