The "October Theory" is a popular social media trend, primarily on TikTok, that encourages people to treat October as a "second New Year." The concept suggests that this month provides an ideal opportunity for a mid-year reset or "adult back-to-school" season.

The Mid-Autumn Festival (also known as the Moon Festival) is a luminous celebration observed across East and Southeast Asia, typically falling on the 15th day of the eighth month of the Chinese lunisolar calendar. It's a time when the moon is at its fullest and brightest, symbolizing reunion, harmony, and gratitude.
