Why is Oktoberfest called „Oktober"-fest when it actually begins in September?

"The historical background: the first Oktoberfest was held in the year 1810 in honor of the Bavarian Crown Prince Ludwig’s marriage to Princess Therese von Sachsen-Hildburghausen. The festivities began on October 12, 1810 and ended on October 17th with a horse race. In the following years, the celebrations were repeated and, later, the festival was prolonged and moved forward into September.By moving the festivities up, it allowed for better weather conditions. Because the September nights were warmer, the visitors were able to enjoy the gardens outside the tents and the stroll over “die Wiesen” or the fields much longer without feeling chilly. Historically, the last Oktoberfest weekend was in October and this tradition continues into present times."

=) Yeah! Last weekend began the Oktoberfest, one of the most important festivals around the world. Unfortunately, during the weekend it was sooo crowded that I couldn't manage to get into a "Zelt" (but at least I could try the roller coaster :)

After that, we went to the cinema ("So ist Paris").

On Sunday morning, it took place the so called "Umzug", an exhibition of typical dresses ("Trachten"). I will upload some photos so that you can have an idea ;)
