Jewish traditions regarding the Sabbath at the time of Jesus? What are some of the Jewish (mishnaic) traditions regarding keeping the Sabbath, that were not specified in Torah? I am interested in knowing the traditions especially prevalent during the time of Jesus. Kindly cite either the scripture or authentic Jewish sources. 

An example would be the "Sabbath Day's Journey":


  KJV Acts 1:12 Then returned they unto Jerusalem from the mount called Olivet, which is from Jerusalem a sabbath day's journey.


I have heard that this is a tradition described by the Jews as a lawful distance that can be traveled on Sabbath. But don't have any Jewish sources. 

Edit 1: By Mishnaic I meant the traditions that were in existence during the time of Jesus. I gather that Mishna is a compiled written form of these traditions that were created during the time intervening between Malachi and Jesus.

Further clarification:


This question is particularly relevant here at Christianity, as I am interested in traditions that the Jews accused Jesus of breaking, especially regarding those on Sabbath.
I am not interested in just Sabbath Day's Journey - but others like it. So it is not a duplicate.
Jewish traditions regarding the Sabbath at the time of Jesus?


  Then returned they unto Jerusalem from the mount called Olivet, which is from Jerusalem a sabbath day's journey. - Acts 1:12 KJV


Josephus makes the Mount of Olives to be about six stadia from Jerusalem and it is thus the acceptable distance between these two places which in Acts 1:12 is given as a Sabbath day's journey. 


  The Jewish scruple to go more than 2000 paces from his city on the Sabbath is referred to by Origen (περὶ ἀρχων, 4, 2), by Jerome (Ad Algasiam, qu. 10), and by Oecumenius — with some apparent difference between them as to the measurement. Jerome gives Akiba, Simeon, and Hillel as the authorities for the lawful distance.
  
  Another reason for fixing the distance of a Sabbath day's walk or journey at 2000 yards is that the fields of the suburbs for the pasture of the flocks and herds belonging to the Levites measured 2000 cubits or yards, and that in Ex 21:13 it is said, "I will appoint thee a place (מקו ם) whither he shall flee" — i.e. the Levitical suburbs or cities. Now, it is argued, if one who committed murder accidentally was allowed to undertake this journey of 2000 yards on a Sabbath without violating the sanctity of the day, innocent people may do the same. Besides, the place of refuge is termed מקו ם, which is the same word employed in Ex 16:29. As the one מקו ם, place, was 2000 yards distant, it is inferred, according to the rule the analogy of ideas or words (גזרה שוה) that the command, "Let no man go out of his place (ממקמו) on the seventh day" (Ex 16:29) means not to exceed the distance of the place 2000 yards off (Hillel I, rule 2, in Erubin, 51 a; Maccoth, 12 b; Zebachim, 117 a). Josephus (War, 5, 2, 3) makes the Mount of Olives to be about six stadia from Jerusalem; and it is the distance between these two places which in Ac 1; Ac 12 is given as a Sabbath day's journey. Josephus elsewhere determines the same distance as five stadia (Ant. 20, 8, 6); but both were probably loose statements rather than measured distances; and both are below the ordinary estimate of 2000 cubits. Taking all circumstances into account, it seems likely that the ordinary Sabbath day's journey was a somewhat loosely determined distance, seldom more than the whole and seldom less than three quarters of a geographical mile.
