I went back and looked at 6 years of certificates to verify the code and they all state the same "Date of Next Audit" and "Expires" dates which for us are, November 7th (Date of Next Audit) and January 21st (Expires), every year. 4 of the audits were actually in November, one was in December and one in October. The next audit and expiry dates should not move around unless you make that change by scheduling it for a different, earlier date or switch certifying bodies and moving the date but that could also be an issue if you are pushing it back. If you have a disaster that interrupts the cycl you have to ask permission from your CB to extend your certification but it shouldn't change that initial date, the next cycle you would revert back to the initial certification date. Specifically section 4.3, para 2 of the "Implementing and Maintaining the SQF Food Safety Code" states "The re-certification audit shall be conducted within thirty (30) calendar days either side of the anniversary of the last day of the initial certification audit." The key is "either side of the anniversary of the last day of the initial certification audit." If it's your first certification, that sets the date for all future re-certifications unless you are granted a change in date in writing and then can only be an earlier date than the original, or as stated before, change of CB. hope this helps clear up some confusion.
