Timing Requirements for Loan Estimate and Closing Disclosure

Question - For the loan estimate, a business day is considered a day on which the creditor's offices are open to the public for substantially all business functions. For the closing disclosure, a business day is regarded as all calendar days except Sundays and the legal public holidays specified, of which the rule and the Consumer Financial Protection Bureau's Small Entity Guide for TILA/RESPA Guide mentions 10 holidays. We are open on four out of the 10 public holidays specified. How does this affect the timing requirements for both the loan estimate and closing disclosure?
