Reply To: Where it says that there is a jiyub to put on Tfillin every day?

If you are going to sit behind a shtender shteiging 24×7, except for sleeping and and periodic asher yatzar moments, than its certainly possible to wear tefillin all day, every day (other than shabbos/yom tovim). However, for 90 percent of the tzibur who in the real world have to go out and work fo a parnassah, whether a farmer working the fields, a skilled worker in construction or a professional working in a laboratory or computer faciliy, you are fortunate to have an 30-45 minutes in the AM to put on teffiilin during shachris.
