Mid-Autumn Festival is held on the 15th day of the eighth month of the Chinese calendar, which is in September or early October in the Gregorian calendar.
In 2015 it takes place on Sunday September 27th. Chinese people will have a two-day "public holiday" on the 26th and 27th — a normal weekend off for 5-day week workers, however...
When Mid-Autumn occurs at the end of September or early October its statutory day of public holiday is usually combined with the statutory National Day three-day holiday for a seven-day public holiday (October 1–7), sacrificing one adjacent weekend day ( for example, in 2015 people need to work on Saturday, October 10).
See below for how the date of Mid-Autumn Day varies in the coming years.
