The Scottish Professional Football League season begins on Saturday with three Premiership ties and 14 other matches in the lower divisions.
First division champions Dundee host Kilmarnock and play-off winners Hamilton Academical welcome Inverness, while St Mirren travel to Motherwell.
Hibernian begin their Championship campaign at home to Livingston - one of four games in the second tier.
And there is a full card in both Leagues One and Two.
On Sunday, promoted Rangers host relegated Hearts in the Championship before two more Premiership encounters complete the weekend's action.
Dundee United travel to take on Aberdeen while St Johnstone welcome Ross County.
Top-flight champions Celtic, whose ground was used during the Glasgow 2014 Commonwealth Games, do not play their first league match until Wednesday, when they face St Johnstone.
It will be a strange season for the Hoops with no Rangers, Hibs or Hearts in the top flight. The biggest 'derby' will be the Dundee derby.
