Are you referring to the Hebrew calendar? If so, you'll find everything you need for "rabbi time."
The concept of a rabbi was extremely new in Paul's time, and he probably didn't study under one. Sages of the time didn't have formal recognition or title.
He was born around the same time as Rabbi Akiva. Around the year 15 CE.
Just a very few examples: Rabbi Yochanan ben Zakkai, Rabbi Yonatan ben Uziel, Chanina ben Dosa, Bava ben Buta, Shimon ben Hillel, Rabbi Eliezer, Rabbi Yehoshua, Rabbi Yossi haKohen, Rabbi Shimon ben Netanel, Rabbi Elazar ben Arakh, Rabbi Yochanan ben Nuri, Rabbi Akiva, Rabbi Nechuniah, Rabbi Nachum Gamzu, Rabbi Yossi Glili, Rabbi Honi Me'agel, Rabbi Abba Shaul, and hundreds of others. Each of these had large groups of disciples, most of whom were Torah-teachers too.
The same way that they had survived until that time: through the continued handing down of Jewish traditions (the Torah) among the sages and their disciples, and the Jewish communities in general. Specifically, the year 132 CE was about the time that Rabbi Akiva died. His greatest disciples (Rabbi Meir, Rabbi Yehuda, Rabbi Yossi, Rabbi Shimon bar Yochai and Rabbi Nehemiah) each headed a yeshiva (Torah-academy) of his own, and (as well as teaching) they strived to lead the Jewish communities through the hard times (132 CE was around the time of the Roman destruction of the city of Beitar).
Originally, it was a rabbi, a rabbi, and a rabbi walk into a bar. . .

Rabbi Aaron Teitelbaum and Rabbi Zalman Leib Teitelbaum
Elie told Rabbi Eliahu that he didn't see his son to spare the rabbi's feelings and provide him with a sense of hope. The rabbi was searching for his son, who had abandoned him during the march, and Elie did not want to reveal the painful truth about the son's betrayal. By withholding this information, Elie aimed to protect the rabbi from despair in a time of immense suffering and loss.
