The application date for trademark registration is usually based on one of the following situations:

1. Actual submission date: The application date of a trademark registration application can be the date of actual submission of the application. This means that when you formally submit the complete trademark registration application documents to the trademark registration agency and pay the corresponding application fees, this date will be regarded as the application date.

2. Priority date: In some countries and regions, trademark registration applicants can enjoy priority based on the date of previous applications in other countries or regions. This means that if you have applied for the same trademark in other countries or regions, and it meets the requirements of relevant international conventions or agreements, you can cite the priority date as the filing date in subsequent applications.

3. Public announcement date: In some countries and regions, the filing date of a trademark registration application can be the date of public announcement. In this case, the trademark registration application will be reviewed first and then enter the announcement period. After the announcement period, the application date will be regarded as the announcement date.

The specific method of determining the date of trademark registration application may vary by country and region. During the trademark registration process, the trademark registration agency will record and confirm the application date and reflect it in the trademark registration certificate.

Please note that the filing date for trademark registration is important in determining rights and priority, but specific regulations may vary from country to country. Therefore, during the trademark registration process, it is recommended to consult the local trademark registration agency or trademark agency to obtain accurate information and guidance.
