halacha - Why does one have to put on Tefillin every day?


Technically, one should wear Tefillin all day. We don't, since we can't keep ourselves clean the whole day.


But we still put it on once a day during Shacharis, since we can presumably keep ourselves clean for such a short period of time.


But lets say one didn't put on Tefillin by Shacharis. Say one was sick, or forgot them at home, or wasn't allowed to due to Tisha BeAv.


The Halacha is one should put them on sometime during the day (or Mincha). Why?


What's the source for our current practice that "one should not let a day go by without wearing Tefillin"?
