Month Day
A date in a calendar is a reference to a particular day represented within a calendar system. The calendar date allows the specific day to be identified. The number of days between two dates may be calculated. For example, "24 December 2012" is ten days after "14 December 2012" in the Gregorian calendar. The date of a particular event depends on the observed time zone. For example the air attack on Pearl Harbor that began at 7:48 a.m. Hawaiian time on December 7, 1941 took place at 3:18 a.m. December 8 in Japan (Japan Standard Time).
A particular day may be represented by a different date in another calendar as in the Gregorian calendar and the Julian calendar, which have been used simultaneously in different places. In most calendar systems, the date consists of three parts: the day of month, month, and the year. There may also be additional parts, such as the day of week. Years are usually counted from a particular starting point, usually called the epoch, with era referring to the particular period of time (Note the different use of the terms in geology).
The most widely used epoch is a conventional birthdate of Jesus (which was established by Dionysius Exiguus in the sixth century). A date without the year part may also be referred to as a date or calendar date (such as "17 December" rather than "17 December 2012"). As such, it defines the day of an annual event, such as a birthday or Christmas on 25 December.
Many computer systems internally store points in time in Unix time format or some other System time format. The date (Unix) command -- internally using the C date and time functions -- can be used to convert that internal representation of a point in time to most of the date representations shown here.

Famous quotes containing the words month and/or day:
“For myself I found that the occupation of a day-laborer was the most independent of any, especially as it required only thirty or forty days in a year to support one. The laborer’s day ends with the going down of the sun, and he is then free to devote himself to his chosen pursuit, independent of his labor; but his employer, who speculates from month to month, has no respite from one end of the year to the other.”
—Henry David Thoreau (1817–1862)
“Play the man, Master Ridley; we shall this day light such a candle, by God’s grace, in England, as I trust shall never be put out.”
—Hugh Latimer (1485–1555)
