What should I pay attention to when choosing the date of school banquet?

I didn't pay attention to the date of the school banquet.

School banquets generally refer to teachers' banquets. Respecting teachers and valuing morality is a traditional virtue of China for thousands of years. When children go to school, parents always thank their teachers, and the thank-you banquet comes into being. Teachers can express their gratitude to teachers or choose to send their own cards.
