Example: Query the Number of Quarters from the Beginning of the Calendar - Advanced SQL Engine - Teradata Database

If the current date is May 5, 1901, the following query returns 6 because May 5, 1901, is in the 6th quarter since 1900-01-01, the beginning of the Teradata calendar:

SELECT TD_SYSFNLIB.QUARTERNUMBER_OF_CALENDAR(CURRENT_DATE);
