<day>

Day

Numeric, two-digit value of the day of the month.

Remarks

The <day> element names a day of the month, in two-digit form as it would be stated as the “DD” in the international date format YYYY-MM-DD (for example, “03” for the third, “25” for the twenty-fifth).
Used in both the article metadata (<article-meta>) and within bibliographic references (<element-citation> and <mixed-citation>).
