What format is described by 'YYYY-MM-DD' for dates?

Explanation:
The string "YYYY-MM-DD" is the ISO 8601 date format: year-month-day with four, two, and two digits, separated by hyphens. When you write a date literal in this form, databases interpret it as a value of the DATE type, which stores calendar dates without time and allows proper date comparisons and arithmetic. It’s not raw binary data or generic text; binary would be unreadable bits, and VARCHAR is a text type. The emphasis on the format indicates a date literal, so this aligns with the DATE format.
