Northern Ireland will kick-off their UEFA Nations League campaign at home to Greece on June 2.
It will be the first of four games in 11 days for Ian Baraclough's side in a quadruple-header to open the competition.
Northern Ireland will also be away to either Cyprus or Estonia on June 5 before travelling to Kosovo on June 9 and hosting Cyprus or Estonia in Belfast three days later.
They will complete their Group C2 campaign at home to Kosovo on September 24 before facing Greece away three days later.
The games against Greece will bring back fond memories for Northern Ireland.
Michael O'Neill's side beat the Greeks home and away to qualify for Euro 2016, including a 3-1 win at Windsor Park which clinched their place at the finals.
New manager Baraclough will be hoping for an improved Nations League performance following Northern Ireland's relegation from League B last time out.
They failed to win any of their six games, drawing twice with Romania and losing home and away to Norway and Austria.
This is the third edition of the Nations League, with former boss O'Neill also failing to win a game during the inaugural competition in 2018-19.
