The word is made up of 'Woche' (week) and 'Ende' (end). So it literally describes the end of the week.
Endlich ist Freitag, das Wochenende steht vor der Tür.
Finally it's Friday; the weekend is just around the corner.
The most common preposition is 'am' for indicating time. To express a duration, you use 'übers Wochenende' (over the weekend). The transition into free time is described with 'ins Wochenende' (into the weekend).
Wir fahren am Wochenende an den See.
We're going to the lake on the weekend.
At the end of the workweek, people often wish each other 'Schönes Wochenende!' (Have a nice weekend!) or 'Erholsames Wochenende!' (Have a restful weekend!). These wishes can stand alone as complete sentences.
Wir sehen uns Montag. Schönes Wochenende!
See you Monday. Have a nice weekend!
week
'die Woche' and 'das Wochenende' are often opposites. 'die Woche' means either seven days or, in everyday language, especially the workdays from Monday to Friday. 'das Wochenende' usually means Saturday and Sunday, that is, the time after the workweek. When someone says 'unter der Woche' (during the week), they normally do not mean Saturday and Sunday. 'am Wochenende' (on the weekend) fits when talking about free time, rest, or plans for Saturday and Sunday.

Das Wochenende ist frei, deshalb besucht Tom seine Eltern.
The weekend is free, so Tom is visiting his parents.
