In PostgreSQL you can use the EXTRACT() function to get the month from a date.

You can also use the DATE_PART() function to do the same thing.

Example 1: The EXTRACT() Function

Here’s an example of using the EXTRACT() function to extract the month from a date.

SELECT EXTRACT(
    MONTH FROM TIMESTAMP '2020-12-16 10:41:35'
    ) AS "Month";

Result:

 Month 
-------
    12

Here’s another example using the current timestamp.

SELECT 
  current_timestamp,
  EXTRACT(
    MONTH FROM current_timestamp
    ) AS "Month";

Result:

      current_timestamp       | Month 
------------------------------+-------
 2020-03-05 09:15:19.89834+10 |     3

Example 2: The DATE_PART() Function

Here’s an example of using the DATE_PART() function instead.

SELECT 
  current_timestamp,
  DATE_PART(
    'month', current_timestamp
    ) AS "Month";

Result:

       current_timestamp       | Month 
-------------------------------+-------
 2020-03-05 09:16:53.587544+10 |     3
