The condition WHERE co.operation_date >= DATE_SUB(NOW(), INTERVAL 3 MONTH) filters records, selecting only those where the operation date (operation_date) is not older than three months from the current date and time.
The NOW() function returns the current date and time, and DATE_SUB subtracts the specified interval — in this case, 3 months — from it. Thus, the query selects all operations that occurred within the last 3 months, inclusive.
