Menachot 36: When to Wear Tefilin

Some brief thoughts regarding today's daf:

• the refilling are considered a positive time-bound mitzvah
• When do we NOT wear tefillin?
• During the day and some of the day, excluding Shabbat/festivals?  Rabbi Yosei Ha Gelili
• When we need an ot, a sign?  If we have a sign, we do not need a sign - this would exclude Shabbat and holidays
• Some believe it is belittling the holiness of Shabbat to were tefilin.  
• The Sages forbid people from wearing tefilin on Shabat in public
