==Who is obligated? Who is exempt?==
# All men above the age of thirteen are required to put on [[
tefillin]] daily. <ref> The Rambam (Sefer HaMitzvot Mitzvah Aseh 12 and 13) and Sefer HaChinuch (421) record this as a mitzvah that applies to every male individual even nowadays. Rambam there says based on the gemara in Menachot 44a that one who is obligated to wear [[ tefillin]] but doesn't, transgresses eight commandments (4 for the hand and 4 for the head). </ref># The common minhag is that a minor wears [[Tefillin]] only 2 or 3 months before his [[Bar Mitzvah]].<ref>Kitzur S"A 10:24</ref># [[Tefillin]] is a [[Mitzvah Aseh SheHaZman Grama]] (time bound mitzvah) and so women are exempt. Even though usually women are allowed to fulfill mitzvot from which they are exempt, by [[Tefillin]] it’s preferable that women do not fulfill this mitzvah. <ref> S”A and Rama 38:3, Mitzvat Nashim (pg 35). Gra in his comments to 38:3 writes that it is forbidden for women to wear [[ tefillin]]. See Targum Yonatan Ben Uziel on Devarim 22:5 who includes a woman wearing [[Tefillin]] in the category of Lo Yehey Kli Gever Al Isha. </ref> Some maintain strongly that women should not wear [[Tefillin]]. <ref> * Rav Hershel Schachter in a letter dated Adar I 5774 (February 2014) explains his position on this topic of women wearing [[Tefillin]] as follows:* The Rabbis of the Mishna felt the need to display their disagreement with the Seddukim even when the Sedukki opinion was a stringency, such as it was regarding Parah Adumah. Nonetheless, because the Rabbis noticed that their opinion was anti-Torah SheBaal Peh, in cases of disagreement the Rabbis made their position very evident. * When developing new minhagim such as women wearing [[Tefillin]], [[Tzitzit]], or [[Kippah]], there is an obvious need to consult with a leading posek of the generation. It is a mistake to think that everyone who went to Yeshiva and knows how to find the right seforim, sometimes by searching online, should be able decide halacha. Real questions of minhag and halacha should be presented to a major posek, who deals with the difficult halachic questions of the generation.
* Women wearing [[Tefillin]] is a symbol of the Conservative movement and it is crucial that the Orthodox community distinguishes itself. It is irrelevant to what extent woman can volunteer by the mitzvah of [[Tefillin]] because in our context, this is a clear symbol of the Conservative movement. As a precedent, Rav Soloveitchik absolutely forbad performing a Bat Mitzvah in the middle of [[davening]] similar to a [[Bar Mitzvah]], the way the Conservatives did.
* Additionally, see Rabbi Mansour on [http://www.dailyhalacha.com/displayRead.asp?readID=2641 dailyhalacha.com] on this topic who also writes clearly that women should not wear [[
tefillin]]. see also Kaf Hachaim 38:9 * see also Rabbi Moshe Feinstein (Sh"t Iggerot Moshe OC 4:49) where he opposes any attempt to allow women to wear [[ tefillin]]. </ref># One who is shirtless cannot wear [[ tefillin]]. <ref> Kitzur S"A of Rav Rephael Baruch Toledano siman 10, who is obligated in [[ tefillin]] and who is exempt, seif 2 </ref># One who is unable to control his promiscuous thought is exempt from [[ tefillin]]. <ref> Kitzur S"A of Rav Rephael Baruch Toledano, siman 10, who is obligated in [[ tefillin]] and who is exempt, seif 5 </ref>
