Mitzvot Aseh SheHazman Grama

1. Women are exempt from all mitzvot Aseh Shehazman Grama with a few execptions as will be listed.
2. If a women wants to do a Mitzvah that she is exempt from she is permitted and encouraged to do so. Ashkenazim hold that women can make a bracha on such mitzvot even though they are exempt, while Sephardim hold that women can't make a bracha since they are exempt.

Daily מצות

1. Tzitzit is a Mitzvah Aseh SheHaZman Grama and so women are exempt. Even though usually women are allowed to fulfill מצות from which they are exempt, by Tzitzit it’s preferable that women do not fulfill this mitzvah.
2. Tefillin is a Mitzvah Aseh SheHaZman Grama and so women are exempt. Even though usually women are allowed to fulfill מצות from which they are exempt, by Tzitzit it’s preferable that women do not fulfill this mitzvah.
3. Tefilla is a Mitzvah Aseh SheHaZman Grama but nonetheless women are obligated in praying once a day and it’s praiseworthy to pray three times a day. There is a dispute regarding Mussaf; see further Sh”t Yabea Omer 2:6(7).

Brachot

1. Regarding the mitzvah of saying one hundred Brachot each day some consider it a Mitzvah Aseh SheZman Grama, while others disagree.

• Rav Elyashiv in Yashiv Moshe (pg 19) and Birkat Eitan (pg 61), **Rav Shechter in “Women at Prayer” at yu.edu, Rav Ovadyah in Halichot Olam (vol 1 pg 59) and Yalkut Yosef (Otzer Dinim LeIsha pg 75), and Hilchot Bat Yisrael (end of chapter 14) write that a women is obligated since it’s a obligation that applies the whole day and is renewed every day similar to the Shagat Aryeh regarding Zecher Yetziat Mitzrayim in Shema. However, Halichot Bayita 13:1 in name of Rav Shlomo Zalman, Sh”t Teshuvot VeHanhagot 2:129, Sh”t Shevet HaKehati 3:63, Birkat Eitan (pg 62), Vezot HaBracha (pg 185, chapter 20), Sh”t Atret Paz 1:1, Shevet HaLevi 5:23, and Sh”t Rivevot Efraim 3:47, 5:114 write that a women is exempt and some base it on the Magan Avraham regarding Zecher Yetziat Mitzrayim in Shema who disagrees with the Shagat Aryeh.

Shabbat

1. Some say that there’s an obligation of women to hear Kriyat HaTorah but the minhag is to lenient in this regard.
2. Women are obligated in Melaveh Malka.

Holidays

1. The Shitat HaKadmonim (last page of bava kama) has the Sh”t Maharam Chavallah (a rishon; the Sh”t was written by the Maharam Challavah’s son in name of his father) which writes that his Rabbi, the Ramban, held that women are obligated in Sefirah (See Ramban Kiddushin 34a). The Maharam Challavah explains that since the time doesn’t cause the mitzvah it’s not considered “Zman Grama”. It happens to be time-bound since of another factor which is that the mitzvah of Sefirah depends on the Korban Omer which itself is bound by time. The Sh”t Maharam Challavah compares it to the obligation on women to eat Shabbat meals which require birkat hamazon. That doesn’t make birkat hamazon a mitzvah Aseh SheZman Grama because the birkat hamazon is obligated as a result of the meal which itself is time bound.

מצות that don’t apply nowadays

1. Turei Even (Chagigah 15) writes that Semicha on a Korban isn’t a Mitzvah Aseh SheHaZman Grama since the mitzvah doesn’t have a fixed time. Regarding Tefillin there’s one day to do it and afterwards the mitzvah is lost and there’s a new Mitzvah to wear Tefillin. However, by Semicha that same Mitzvah could be done any day during the daytime. [See Minchat Elazar 2:47’s second reason regarding the building of the Bet HaMikdash.]
2. The Rambam (Bet HaBechirah 1:12) writes that everyone is obligated in building the Bet HaMikdash. The questioner in Sh”t Shoel UMeshiv Tanina 3:89 (beginning paragraph D”H Heneh) inquires as to why women are obligated since it’s a mitzvah that only applies during the day and being a time-bound mitzvah, women should be exempt.

• However, the Sh”t Shoel UMeshiv answers that because men are obligated, women are also obligated. The reason for this is since the whole reason of a women being exempt is that women are subservient to their husbands and don’t have time to fulfill time-bound מצות, however since their husbands are obligated, they too can fulfill this mitzvah properly.
• Alternatively, the Sh”t Minchat Elazar 2:47 writes that since the mitzvah includes donations to the Bet HaMikdash which can be given at night as well, then it’s not considered a time bound mitzvah. [My (Ike Sultan) difficulty with this answer is that the mitzvah should still be time bound since one can’t build nor donate to the Mikdash on Shabbat and holidays.]
• The Minchat Elazar’s second reason is that since the mitzvah is incomplete and could continued to be fulfilled each day, then, even if the mitzvah doesn’t apply during the night, still it’s considered not time-bound unlike Tefillin which is time bound and once the day passes there’s a new mitzvah to fulfill. [See Turei Even regarding Semicha.]
