GROUP BY MONTH(DateBilled) misses an entry consistently

Hello I've got the following SQL Query, which consistently pulls up only 3 out of 4 months from the database: $sql = " SELECT COUNT(DateBilled) AS count, MONTH(DateBilled) AS BilledMonth, YEAR(DateBilled) AS BilledYear FROM Invoices GROUP BY MONTH(DateBilled) ORDER BY DateBilled ASC"; This results in: Month: November Number of Invoices: 17 Month: December Number of Invoices: 22 Month: January Number of Invoices: 15 But when I do change the order of the query from ASC to DESC like this: $sql = " SELECT COUNT(DateBilled) AS count, MONTH(DateBilled) AS BilledMonth, YEAR(DateBilled) AS BilledYear FROM Invoices GROUP BY MONTH(DateBilled) ORDER BY DateBilled ASC";$sql = " SELECT COUNT(DateBilled) AS count, MONTH(DateBilled) AS BilledMonth, YEAR(DateBilled) AS BilledYear FROM Invoices GROUP BY MONTH(DateBilled) ORDER BY DateBilled DESC"; I get: Month: December Number of Invoices: 22 Month: November Number of Invoices: 17 Month: October Number of Invoices: 21 (I gained October and Lost January) The date format in the DB is like this: 2001-12-05 I've tried a whole stack of variations on the above query, but I still seem to be coming up one short. Any idea why I'm not getting a display of all of the months? Thanks.
