That's because these two months are chock-full of what is known as High Holy Days, said Temple Har Shalom's interim rabbi Jim Simon.
"If you look in the Torah, or the five books of Moses, you will see that there is a mention of the Jewish New Year, Rosh Hashanah," Simon said during an interview with The Park Record. "It says that seven days after Rosh Hashanah we are to observe a day of atonement, which, in Hebrew, is Yom Kippur."
Furthermore, there is another reference to the fall harvest, a feast celebration, which is called Sukkot, he said.
"That's also known as the feast of the booths," Simon explained. "At the end of Sukkot, there is to be an eighth day of rejoicing, which has developed into the holiday Simchat Torah that is about rejoicing with the Torah.
"So you see, the Jewish people aren't the ones who determine when we hold these holidays," he said. "It's determined by God and the Torah."
This year, the Holy Days, which are also referred to as holidays, will begin with the Selichot observance at the Temple that will feature a screening of Albert Brooks' 1991 comedy "Defending Your Life."
Selichot are poems and prayers that will be recited during a service after the screening.
Then on select days from Sept. 4 through September 25, the Holy Days kicks into high gear, Simon said.
"They are all very busy times and not just times of great joy and happiness, but they are times of great seriousness and intense serious reflection," he explained. "(We) reflect all the things that should be happening in our lives, because our lives are not just about joy, happiness and fun, but also filled with seriousness."
The Jewish community uses the holidays to also look at what kind of people they are and how their behavior was during the previous year.
" the end of the holidays, we pretty much have run the whole gamut of emotions," Simon said.
When congregations throughout the world observe the holidays, there are certain ordinances that are uniform, but done is a way that is unique to each congregation, Simon explained.
"If I could take you into almost every synagogue in the world — Reformed, Conservative or Orthodox — for Rosh Hashanah, you will hear a number of prayers that are set, common and intrinsic to the holiday," he said. "Those prayers reflect the main themes of Rosh Hashanah. The prayers used in Yom Kippur are the same as well.
"However, every synagogue adds its own wrinkle and emphasis or cultural traditions to the services," Simon said. "So there is a great similarity, but there are some differences based on the congregation, its history and culture."
Simon, however, will not try to add his own traditional interpretations to the services that will take place at Temple Har Shalom for logistical reasons.
"I'm in an unusual situation because I'm the interim rabbi," said Simon, who has replaced outgoing rabbi Joshua Aaronson. "I have come to Park City for one year to help the congregation find a new rabbi and to help them resolve any outstanding issues before the new rabbi comes.
"So on one hand, it is already a big change for the Temple that I'm here, and the last thing I want to do is introduce new changes," he said. "My general inclination will be whatever the customs of the congregation has been during these High Holy Days will not change, because I want this year to have some stability and continuity."
Simon entered rabbinical school in the San Francisco Bay Area when he was 28, after two years of practicing law.
"I gave up my job and began to get more involved in Jewish traditions because they had a strong pull on me," he said. "It was a perfect fit for me and ordained in 1983 and became a pulpit rabbi."
Upon graduation, he was selected with a group of 15 to be trained to become interim rabbis that went into congregations that have experienced change.
"Our goal was to set a relaxed tone so the congregations could catch their breaths and prepare for the future," he said.
Simon's hope for the Temple Har Shalom members is that they can move from the past and embrace the future.
"I don't mean that they forget about the past, but I don't want them to let it become a big burden on their shoulders," he said.
