The Aslan frontman will be laid to rest in a private funeral following a public gathering in Finglas.
According to RIP.ie, his funeral cortege will travel through his local community, allowing people to pay their final respects.
It will begin at the junction of Tolka Valley Road and Cardiffsbridge Road at 9.45am, before travelling north on the Cardiffsbridge Road, and then south-west towards Farnham Drive.
The cortege will conclude with a public gathering at a playing field opposite Erin’s Isle GAA Club to pause for a video tribute and depart at 10.15am.
A private funeral for friends and family will be held following the public gathering. Mr Dignam’s family has asked sympathisers to donate to Saint Francis Hospice in lieu of flowers.
Mr Dignam died peacefully with his family by his side after battling cancer on Tuesday afternoon.
President Michael D Higgins led the tributes to him, saying "all of us have been struck by the dignity with which Christy lived with his illness".
According to RIP.ie, the 63-year-old singer earned his place as a "rock legend" as frontman to rock band Aslan, “while remaining true to his Finglas roots”.
“Christy’s songs and voice provided the backdrop to successive generations, enraptured by his lyrics, his passion and his stage presence,” the obituary said.
“[He was] a generous supporter of countless charity events, often turning up at the bedsides of admirers who were ill.”
Mr Dignam is survived by his wife Kathryn, his daughter Kiera, grandchildren Cian, Ava and Jake, son-in-law Darren, and his sisters and brothers Bernadette, Deirdre, James, Brian, Therese, Jackie and Eddie.
He is also remembered by his fellow Aslan members, neighbours, and friends.
