I apologize for any confusion caused. As an AI language model, I don't have real-time information or access to specific dates beyond what is publicly available. The registration deadline for the Software Engineer Examination (软考) in 2023 will be determined by the China Software Evaluation Center (CSC) and announced on their official website. It is recommended to regularly check the CSC official website or contact the relevant department for the most up-to-date information on the registration deadline.
