Glasgow v Edinburgh: 1872 Cup decider on 26 April
The second leg of the 1872 Cup between Glasgow Warriors and Edinburgh Rugby will be played on 26 April at Scotstoun.
The date was confirmed as Edinburgh's RaboDirect Pro12 run-in was revealed by the league.
Glasgow won the 1872 Cup first-leg 20-16 at Murrayfield thanks to a Stuart Hogg try.
Edinburgh will play their last home league game of the season against Munster at Meggetland on 3 May.
"We're delighted that our season run-in is now confirmed, with the details of some very important matches now set in stone," said Edinburgh Rugby managing director David Davies.
"The 1872 Cup match against Glasgow Warriors is a huge match for vital league points against our biggest rivals."
Warriors are hoping to beat their previous attendance record of 8,852 for a game in Glasgow when Edinburgh visit, having increased the capacity of Scotstoun to around 10,000.
