Example: Querying the Saturday Before a DATE or TIMESTAMP - Analytics Database - Teradata Vantage

The following SQL statement:

SELECT TD_SATURDAY(TIMESTAMP'2012-05-08 10:00:00',NULL,TIME'05:00:00+03:00');

returns 2012-05-05 02:00:00.

where NULL indicates the session calendar, which in this case is TERADATA.
