France does not have 12 time zones; it operates on a single time zone known as Central European Time (CET), which is UTC+1 in the winter months and Central European Summer Time (CEST), which is UTC+2 in the summer months. However, France does have overseas territories and regions located in different parts of the world, each following its own time zone based on its geographic location. These territories include French Guiana in South America, Guadeloupe, Martinique, Saint Martin, and Saint Barthélemy in the Caribbean, and various islands in the Indian and Pacific Oceans.
