    Hi,
    The 12-hour clock is a time conversion convention in which the 24 hours of the day are divided into two period called ante meridiem (a.m., Latin: "before mid day" English: "before noon"] and post meridiem (p.m., Latin: "after mid day" English: "after noon").The capitalization and punctuation of a.m. and p.m. may vary (consistently) in different texts. Each period consists of 12 hours numbered 12 (acting as zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11. The indication of noon and midnight in the 12-hour system is disputed.

    The 12-hour clock was developed over time from the mid-second millennium BC to the 16th century AD and was once popular throughout Northern Europe, but is now used as the dominant system in many former British colonies, including the United States and Canada. It is also used informally in most of the world.
