The Fifth Golden Rooster and Hundred Flowers Festival, to be held in southeast city of Kunming from October 9 to 13, will feature award-giving ceremonies, film exhibitions, as well as business exchanges.
The Fifth Golden Rooster and Hundred Flowers Festival takes place in Kunming over 6 days.
The festival is from the 9-13 which is 5 days, not 6.  I think the computer was fooled because it could not compute how many days it lasted.
