Scottish Premier League officials have confirmed that the final Old Firm match of the season at Ibrox will be played on Sunday 24 April (kick-off 1230 BST).
Following consultations between Strathclyde Police, Rangers and Celtic, the date was announced before the rest of the post-split fixtures.
In recent seasons, the SPL has tried to avoid an Old Firm title decider.
Rangers are currently one point ahead of Celtic in the title race, having played one match more.
Police are normally keen to avoid the match going ahead on a bank holiday weekend, but the first two weekends after the split are both holiday weekends.
No other post-split fixtures have been announced, with Rangers set to play their last pre-split match at Dundee United on 19 April, while Celtic are scheduled to meet Kilmarnock on the following day.
However, the SPL has yet to announce a date for the rearranged fixture between Inverness Caledonian Thistle and Celtic, which was postponed on Saturday due to a waterlogged pitch.
If Inverness fail to reach the top six, that match could be arranged for a date after the league splits in two.
