A legislative period, also known as a SESSION, is a period of time in which a legislature meets to discuss and pass laws. A SESSION typically lasts for a certain amount of time, such as a year or two, and can be divided into multiple parts. During a SESSION, legislators debate and vote on proposed laws, and the laws that are passed become part of the country's legal system. The length of a SESSION varies from country to country, and some countries may have multiple sessions in a single year.
