### Date Identifier This identifier allows you to add dates in the following formats. * Short date (YYMM), for example: 2401 for January 2024. * **YY**: Represents the last two digits of the year. * **MM**: Represents the two digits of the month. * Long date (YYMMDD), for example: 240101 for January 1, 2024. * **YY**: Represents the last two digits of the year. * **MM**: Represents the two digits of the month. * **DD**: Represents the two digits of the day. * Short Julian date (CYYDDD), for example: 2124001 for January 1, 2024. * **C**: Century, typically a single digit. * **YY**: Represents the last two digits of the year within the century. * **DDD**: Represents the day of the year, ranging from 001 to 365 (or 366 in a leap year). The dates that can be chosen are those defined in [**Lot Definition**](https://help.ciqa.net/help-center/ciqa-eqms-user-guide/modules/products-and-inventory-management/products-and-lots/lots-definition); these are the following: * Lot Expiration Date * Lot Manufacture Date (Manufacturing Date) Select **Date** as the identifier, choose a date in the desired format, and press the add icon.
