0200

0200 is a four-digit decimal string that most often appears as a time notation in 24-hour clock format. When used to denote the time of day, 0200 corresponds to two hours after midnight, i.e., 02:00. The leading zeros are used to maintain a fixed width in digital displays and in data records, reducing ambiguity with other times such as 200 or 12:00.

In schedules, timetables, and communications, 0200 hours is a common phrasing in military, aviation, maritime, and emergency services contexts. Referring to times in hours and minutes avoids confusion with AM/PM and supports standardization across regions and systems.

In computing and mathematics, a leading zero can indicate octal notation in some programming languages. As an octal literal, 0200 represents the decimal value 128. In contexts where leading zeros are not octal indicators, 0200 is simply the string of digits 0, 2, 0, 0.

As a numeric value, 0200 may be interpreted as 200 if leading zeros are stripped, or as a year label such as 0200 representing the year 200 CE in historical dating conventions when used in a year field.

Overall, 0200's meaning is context dependent, most commonly a time designation but also encountered as a numeric literal or identifier in technical settings.
