Weather wise, October can be one of Chicago's most beautiful months with crisp, cool temperatures and sunny days. (It can also be a hot month in Chicago, particular in the beginning of the month when temperatures can stay well into the 80s.)
October is also one of Chicago's busiest months with the annual Chicago Marathon, which attracts tens of thousands to the Windy City, as well as Halloween and more.
Here are some fun things to do in Chicago in October 2012 that go beyond the "boo" in Halloween.
September 26, 2012 (sometimes the date is in October): Yom Kippur - Yom Kippur (the Day of Atonement) is one of two Jewish High Holy Days and falls 10 days after Rosh Hashanah on the 10th of Tishrei, which is a Hebrew month that correlates with September-October on the secular calendar. The purpose of Yom Kippur is to bring about reconciliation between people and between individuals and God. According to Jewish tradition, it is also the day when God decides the fate of each human being. (For more information on Jewish holidays in October and throughout the year, read our Jewish Holiday Calendar 5772.)
