3-Day Break for Mooncake Festival 2021
Normally, Chinese people will have a three-day "public holiday" on the Mid-Autumn Festival — 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.
How long do Mid-Autumn Festival celebrations last?
The nationwide public holiday usually lasts 3 days. However, traditionally Chinese people start preparing for the festival 1 week in advance.
Many kindergartens and primary schools in China will hold celebration activities 1 or 2 days before the public holiday. The students are encouraged to make lanterns for classroom decorations, share festival stories with classmates, and/or make festival foods to share with each other.
The Mid-Autumn Festival is also a good gift-giving opportunity. Chinese people may home-make their mooncakes or purchase them as gifts several days in advance, and then send them to their family members, friends, colleagues, or leaders during the festival.

How is the Mid-Autumn Festival date determined?
The Mid-Autumn is celebrated on month 8 day 15 of the Chinese Lunar Calendar, and it always falls in September or October (ranging from about Sep. 6 to Oct. 6)
According to the Chinese lunar calendar (and traditional solar calendar), the 8th month is the second month of autumn. As the four seasons each have three (about-30-day) months on the traditional calendars, day 15 of month 8 is "the middle of autumn".
On the 15th of each lunar calendar month, the moon is at its roundest and brightest, symbolizing togetherness and reunion in Chinese culture. Families get together to express their familial love by eating dinner together, appreciating the moon, eating mooncakes, etc. The harvest moon is traditionally believed to be the brightest of the year.
Month 8 day 15, is traditionally the time rice is supposed to mature and be harvested. So, people celebrate the harvest and worship their gods to show their gratitude.
