Ireland will face Spain on 13 March in what is effectively a semi-final for qualification for the 2021 Rugby World Cup.
Spain beat the Netherlands 87-0 on Saturday afternoon to claim the Rugby Europe Championship 2020 title and will now host Ireland in Madrid.
Should Adam Griggs' side beat Spain, they will play the winners of a match between Scotland and Italy, which is provisionally scheduled for early May. A date for the final will be confirmed following this game.
The winners of the European final qualify automatically for the New Zealand tournament, which was due to be held between 18 September and 16 October but has been postponed until next year.
The losers of that game can still qualify via a world repechage.
Ireland, who held a training camp in Dublin at the weekend, are due to play Wales and France in April in a condensed Women's Six Nations tournament after the original fixtures were disrupted by the coronavirus.
World Rugby are due to confirm details of Ireland's game against Spain soon.
