For example, if someone says "midnight on Sunday," regardless whether they use the 12-hour clock or 24-hour clock it is not possible to know with certainty whether midnight on Sunday refers to the time at which Sunday is ending or beginning without being told. Neither timekeeping method is perfect however, and one of the potential sources of confusion that both methods are susceptible to occurs at midnight (00:00 or 24:00 in the 24-hour click and 12:00 AM in the 12-hour clock). None of the hours in the 24-hour clock repeat, so there is no risk of confusion. The 24-hour clock is also sometimes referred to as military time.

A 24-hour clock is a way of keeping time that divides a day into 24 hours starting from midnight and ending at midnight.
