UEFA have confirmed the remaining Nations League fixtures, pushing the Republic of Ireland's final four games in the competition back by a day or two each and setting up two potential blocks of three games in seven days.
The changes have been made due to the rescheduling of the Euro 2020 play-offs, which were postponed from March to October/November due to the Covid-19 pandemic.
As confirmed last week, Stephen Kenny's first match in charge of the senior side will be in Bulgaria on 3 September followed by a home game against Finland on 6 September.
Ireland will travel to Slovakia for their play-off semi-final on Thursday 8 October and will now host Wales on Sunday 11 October, rather than the day before as initially intended, with the away trip to Finland moving to Wednesday 14 October from the Monday.
If Ireland reach the play-off final, against Bosnia or Northern Ireland, on Thursday 12 November, they will again be playing three games in seven days: the away game in Wales has moved from the Friday to Sunday 15 November and the visit of Bulgaria to Dublin switched from the Monday to Wednesday 18 November.
