When inserting a date into a typical SQL database column of type DATE, the standard input format is:

YYYY-MM-DD (for example: 2024-09-15).

So in an INSERT statement you would usually write something like:

sql

INSERT INTO Orders (order_date)
VALUES ('2024-09-15');

Most SQL engines also store full date‑time values using:

  • DATETIME / TIMESTAMP: YYYY-MM-DD HH:MM:SS (for example: 2024-09-15 14:30:00).

Some databases let you feed dates in other human formats (like 15/09/2024), but they are normally converted to an internal date type and are safest and most portable when given in the canonical YYYY-MM-DD style.
