The reigning champions kicked off the month with a 5-0 win over Ross County in Dingwall then beat St Mirren 2-1 in a rearranged match in Paisley before notching up back-to-back home victories over Livingston (3-2) and Hibernian (3-0).
That took Celtic's winning run in the Premiership to six matches as they moved to within a point of leaders Rangers with a game in hand.
