二週間 is the everyday way to say 'two weeks' as a duration, while 十四日 emphasizes the exact count of 14 days and sounds more literal or formal.

Don't confuse with

四よっ日かN5
十四日 means the 14th (or 14 days) while 四日 means the 4th (or 4 days); the shared 四日 substring and irregular っか readings make them easy to misread.
１３じゅうさん日にち
１３日 is read regularly as じゅうさんにち, but １４日 has the irregular reading じゅうよっか (not じゅうよんにち), which learners often mix up.

Etymology

Compound of 十 (じゅう, ten), 四 (よん, four), and 日 (か, day). The reading よっか is an irregular sound shift from よん + か.
