In addition to the timetable noted in Lucas' comments, this map may be useful:
Zürich is a very nice and quite cosmopolitan city, but is far from the Alps and is not noted for its scenic beauty. Unless you have definite ideas about what you want to do in Zürich, you might instead consider a day or two in Luzern, with the remainder- 2 or 3 days- in the Jungfrau region.
In that region, the best scenery is in the villages several miles from Interlaken, some of which are car free.
You might look at Grindelwald, Lauterbrunnen, Wengen and Mürren as possibilities. All are accessible by frequent trains from Interlaken Ost.
