I'm not quite sure what is being asked in this question, but I assume this has to do either with the time frame of Sophocles' tragedy, the amount of time it took to stage Sophocles' tragedy, or the year in which the tragedy was first staged.
The events portrayed in Sophocles' Antigone occur during the space of a single day. This is typical of Greek tragedies.
Like the plays of all ancient Greek dramatists, Sophocles' plays were also staged on a single day. Most Greek tragedies take about 90 minutes to stage.
Finally, although dating the original date of production for Greek plays can often be a tricky matter, it is well-agreed that Sophocles' Antigone was first staged in 442/441 BCE.
