How to select by month in postgresql?

Question

PostgreSQL

There is an application table with many attributes, but it doesn't matter. The main attribute is the creation date.
What is the best way to sample by month? Or is it better to add additional attributes for the month and year of the application?
Sample needed: November - 2 applications, December - 3 applications, etc.

Answer 1

SELECT date_trunc('month', date_created), count(*)
FROM table_name
GROUP BY date_trunc('month', date_created)
