We are keeping this calendar in GMT/UTC time using a 24-hour clock. Why? We are a global organization and Universal Time Coordinated (UTC) is the international reference time scale maintained by the Bureau International des Poids et Mesures (BIPM). The 24-hour clock is the world’s most widely used time format. It is used in non-English speaking countries in Europe, Latin America, Asia, and Africa, as well as by the military, aviation, and other specialized fields. It is also commonly used for written time representation in many countries. Scroll down below the calendar to see how the 24-hour clock relates to the 12-hour clock.
