It's that time of the year when fans of Scottish football are keen to discover the unknown quantity of the post-split Premiership fixtures.

There is just one matchday left in the regular season in Scotland's top flight, with Dundee vs Rangers also due to take place this week.

Most positions in the table are secured, however, the battle for the top six rages on into game week 33, with Dundee, Hibernian and Motherwell all holding a chance of joining Celtic, Rangers, Hearts, Kilmarnock and St Mirren in the top half of the table for the remaining five games.

Dundee holds the advantage in that they have two games left to play, compared to their rivals - who incidentally play each other at Fir Park on Saturday. Aberdeen will then be Dundee's final opponents as they try to seal that sixth spot.

The fixture list very much depends on which team finishes sixth, and the other two in seventh and eighth. 

But while that much remains a mystery for now, what we do know is that Celtic and Rangers will meet for a fourth time this season - and that encounter is due to be played at Celtic Park.

When will it take place, though? Well, while it's not totally foolproof at this stage, it seems increasingly likely that Glasgow's big two will meet at the start of the post-split fixtures.

This is because the SPFL will not want a title decider occurring any closer to the end of the season due to the magnitude of the derby.

History also tells us that no matter how tight the title race is between the sides, they always seem to play in either the first or second game post-split.

So, looking at the dates for the Premiership's split, this will probably see Rangers travel to Celtic on either the weekend of April 27 & 28 or the weekend of May 4 & 5.

After that powderkeg clash, attention will then turn to the final games - with the very last fixture for the top six coming on Saturday, May 18.

It is anticipated that the fixture list for the last five games of the season will drop early to middle of next week.
