Time for Truth is a campaign for victims and survivors of conflict in the north.
The Day of Action will highlight the group's opposition to British Government's proposals to grant de-facto amnesty to pre-Good Friday Agreement crimes.
Time for Truth says the proposals would close down present and future police and Police Ombudsman investigations, civil actions and legacy inquests.
In the Shannonside region, the Day of Action will be taking place at 12 noon on the bridge in Carrick-on-Shannon, Co Leitrim, and in Market Square in Longford Town.
In the Northern Sound region, events are planning for Main Street, opposite the post office, in Cavan Town and on Church Square, opposite the Court, in Monaghan Town.
