A more thorough explanation:

Definition: Sessions refer to a court of criminal jurisdiction that is held in each county or borough once every quarter of a year. The court is made up of a county's justices of the peace and has the power to try and determine all felonies and trespasses. In some states, sessions are also held four times a year with jurisdiction over misdemeanors and administrative tasks such as the care of public roads and bridges.

• The Court of General Quarter Sessions of the Peace is a type of sessions court that must be held in every county once every quarter of a year. It has the power to try and determine all felonies and trespasses.
• In some states, a Quarter Sessions Court is held four times a year and has jurisdiction over misdemeanors and administrative tasks such as the care of public roads and bridges.

These examples illustrate how sessions courts are held at regular intervals and have the power to try and determine criminal cases. They also show how sessions courts can have different levels of jurisdiction depending on the state or country in which they are held.
