Postponing Management Review

According to the ISO 13485:2016 requirement 5.6.1 Management review General, is stated that Top management must review management system at documented planned intervals to ensure that the system is stable, adequate and efficient. Therefore, if your planned interval is one year, and usually it is done in May, than you should do it in May. If you had shorter interval of doing the management review, then it would be acceptable to postpone it, but since one year is a very long period of time, it is not advisable to postpone it.
