The Ospreys' Champions Cup schedule for the season will be confirmed on Tuesday 22nd August at 3pm.
The dates, venues, kick-off times and television coverage for the matches in Rounds 1 to 4 will be revealed on Ospreys channels and on epcrugby.com and on EPCR's social media channels.
The dates, venues, kick-off times and broadcast details for the matches in Rounds 5 and 6 will be announced in December following the conclusion of the Round 4 fixtures.
Once the Pool Draws for both tournaments are completed, the fixtures are decided by means of a scheduling process which includes consultation with the 40 participating clubs, league bodies and broadcasters across each territory.
EPCR is challenged with producing a balanced and fair schedule which takes into account club preferences, restrictions at many shared stadia, date requests associated with moves to larger venues as well as ensuring that its broadcasters across Europe can cover as many compelling matches as possible from Thursday evening through to Sunday.
EPCR is able to move the scheduling process forward in earnest once the fixtures of all three of Europe's professional leagues are announced.
