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:
“Frankly, I adore your catchy slogan, “Adoption, not Abortion,” although no one has been able to figure out, even with expert counseling, how to use adoption as a method of birth control, or at what time of the month it is most effective.”
—Barbara Ehrenreich (b. 1941)
“Noble and wise men once believed in the music of the spheres: noble and wise men still continue to believe in the “moral significance of existence.” But one day even this sphere-music will no longer be audible to them! They will wake up and take note that their ears were dreaming.”
—Friedrich Nietzsche (1844–1900)
