<P> 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 "29 May" rather than "29 May 2018"). As such, it defines the day of an annual event, such as a birthday or Christmas on 24 / 25 December . </P> <P> Many computer systems internally store points in time in Unix time format or some other system time format .
