DAY

  • Recent Updates: April 04, 2022
  • 1. Overview

    SyntaxDAY(serial_number,format)Returns the day of the date. DAY is a number between 1 and 31.
    Parameterserial_number

    The date containing the year requested. It can also be a series number, such as in a 1900 date system, where January 1, 1998 is stored as a series number of 35796.

    Note: The real-time data serial_number supports only text and date types.

    The DAY() parameter in DAY(serial_number, format) is allowed to be empty. If the parameter is empty, the DAY in the date corresponding to the server time of the current system is used.

    2. Precautions

    • Extracted data allows parameters to be null, supporting two parameters, the first parameter default date or text type, the second default parameter text.

    • Real-time data can use either a default date or a text-type parameter.

    • The second parameter supports the format yyyy-MM-dd.

    3. Example
