Shulchan Aruch was created in 1565.

In principle, tefillin should be worn the whole weekday until sunset (Shulchan Arukh Orach Chaim 30:2); and that is how our ancestors conducted themselves in ancient times. However, due to the spiritual descent which the generations have undergone (Talmud, Shabbat 112b), we now wear the tefillin only during the shacharit (morning) services (Shulchan Arukh Orach Chaim 37:2), since one must maintain a high level of concentration (Talmud, Menachot 36b) and physical purity while wearing the tefillin (Talmud, Shabbat 130a).

We don't wear the Tallit during Maariv or at night, because "and you shall see them" (Bamidbar ch.15) is interpreted to mean "only during the day" (Talmud, Menachot 43a; Shulchan Arukh Orach Chaim 18:1).

In shulchan aruch (code of Jewish law). Also see Mishnah Berurah.

Jewish law is called 'halacha'. Halacha is recorded in the Talmud and the Code of Jewish Law (Shulchan Aruch).
