fixed-term

The word contains the noun 'die Frist' (deadline / time limit), which means 'period of time' or 'deadline.' So 'befristet' (fixed-term) literally means that something has been provided with a deadline, that is, a fixed time limit.
Dieses Sonderangebot ist befristet und gilt nur bis Ende der Woche.
This special offer is fixed-term and is valid only until the end of the week.
To state the exact duration of the fixed term, the preposition 'auf' followed by the accusative is used. This construction is very common.
Meine erste Stelle war auf sechs Monate befristet.
My first position was fixed-term for six months.
This adjective is very often used in the context of work and contracts. Typical combinations are 'ein befristeter Arbeitsvertrag' (a fixed-term employment contract), 'eine befristete Stelle' (a fixed-term position), or 'eine befristete Aufenthaltserlaubnis' (a temporary residence permit).
Viele junge Leute finden nach dem Studium nur eine befristete Stelle.

temporary
Both words describe something that is not permanent. Befristet is used when the beginning or end, or a fixed period, has been specified. Vorübergehend, by contrast, generally indicates a limited duration without requiring an exact end date. Therefore, use befristet with fixed time details and usually vorübergehend otherwise.

She has a fixed-term contract that ends on June 30.
