We will continue to study sales forecasting methods in depth. This time, we will focus on distinguishing national holidays from non-national holidays (non-national holidays, such as regional holidays or specific store promotion days) to analyze the actual impact of different types of holidays on sales in a more detailed manner. After completing the holiday classification and impact assessment, we will build a classification forecasting model based on the obtained data and apply it to sales forecasts for national and non-national holidays respectively.
