All full-time missionaries carry the title of "Elder" (men) or "Sister" (women). These titles are translated into the languages of the country in which they serve. In Italy, for example, the Elders are "Anzianos" and the Sisters are "Sorellas." The missionary's name and the name of the Church is embossed on a name tag which each missionary wears throughout his or her mission.
All full-time LDS missionaries must adhere to a strict set of rules, designed to keep them focused on their work. For safety and other reasons, all missionaries are assigned to work in pairs, called "companionships." A missionary is with his or her companion 24/7. Companionships can change every few weeks and missionaries generally spend 2-4 months in an area before being reassigned somewhere else. Between study, service, proselyting, and teaching, a missionary may spend up to 60 hours a week working. One day a week is set aside as a preparation day (often called "P-Day" by the missionaries). This is generally Monday. On that day, personal errands can take up some time, as well as sightseeing, writing letters (or email), recreation, or other activities.
At the end of a missionary's service, he or she travels back home from the mission field and is released from being a missionary after meeting with his or her stake president.
