During which days must the principal place hours be maintained?

The principal place hours must be maintained Monday through Friday because these days align with the typical business operating schedule in most industries, including automotive sales and service. This time frame allows businesses to effectively interact with customers during standard working hours when the majority of people are available to conduct transactions, inquiries, or gather information.

Maintaining regular hours during this period helps ensure compliance with regulatory standards and fosters a reliable customer service environment. While some businesses may operate on weekends, the requirement specifically emphasizes the weekdays to standardize operations across the industry. Choosing any day of the week doesn't reflect the typical business calendar where most transactions and activities are concentrated during the weekdays.
