Validity and document management

Please note that the validity date refers to the date from which the document starts to be valid and needs to be followed. Normally this date is the one when the document is approved by the document owner.

In your example “This document is valid as of 12 AUG 2024” it means that the document only will be valid to be followed one year from 12 AUG 2023. If you want the document to be followed starting from 12 AUG 2023, the phrase would be “This document is valid as of 12 AUG 2023.”  

So if a document  is not undergoing any change for few years then this date will be very old date (may be 3-4 years)  and hence sometimes creating confusion during  audits. Like to know if as  part of annual review of documents we need to update this date with latest reviewed date even though no changes was done?

This is an acceptable approach compliant with the standard to evidence document review.

Please note that a document review not necessarily needs to lead to changes in it, so you can update the change history of the document to include the information about when the document was last reviewed and that no need to change was identified.
