* How long is Tosefet Shabbat? Rosh Brachot 4:6 and Tosfot Brachot 27a D”H DeRav agree that one doesn’t have to accept Shabbat from Plag Mincha (from ten and three quarter hours). Nonetheless, the Rosh 4:6 writes that certainly there is a minimum time limit but leaves it unclear as to what the limit is. Rabbenu Yonah (Brachot 18b D”H Rav) quotes Rabbi Yacov who says that there’s no minimum time and any amount suffices.

* S"A 271:2 and 608:1 rules that there's no minimum requirement of time one needs to add to Shabbat to fulfill Tosefet Shabbat. 39 Melachos (vol 1, pg 150) rules like S"A that there's no specific minimum time for Tofeset Shabbat.

* However, the Mishna Brurah 271:22 quotes the Rosh who argues that a certain amount of time is needed. Biur Halacha D"H Ayzo Zman posits that this period of time should be no longer than 3/4 of a mil (which is 13.5 minutes). However, Mishna Brurah 271:22 explains that according to the S"A who holds that it's not nighttime until Tzet HaCochavim Tosefet Shabbat and Ben HaShemashot is 30 minutes.

The Mishna Brurah 271:23 concludes that in order to fulfill the mitzvah of Tofeset Shabbat (adding onto Shabbat) one should refrain from work from the time that the sun is seen at the top of the trees, or to be strict 30 or 20 minutes before Shekiyah. [Mishna Brurah (Shaar HaTzion 261:21) explains that by refraining from melacha 20 minutes before sunset one will have satisfied the opinion of the Yerayim to consider the mil to be 24 minutes and 3/4 of a mil is 18 minutes.] 39 Melachos (Rabbi Ribiat, vol 1, pg 145) writes that it's not practical to rely upon the method of determining the beginning of Shabbat by looking at when the sun hits the tree tops but rather one should rely upon times printed on calendars made by halachic experts. </ref>
