With parade times spaced out nicely in Portlaoise, Mountmellick and Portarlington, spectators could do a fun trail, while each town has all day entertainment.
In Portlaoise the morning starts with the Streets of Portlaoise Road races, and a vintage motor run, before the parade kicks off at 12:30 from County Hall.
It goes down JFL Avenue to the church and then up Main Street to the Top Square past the viewing stand, ending on the Mountrath Road.
A street festival continues until 5pm. Children's wristbands for €3 will include bouncing castles, face painters, disco domes and a disco in Coppers.
The Portlaoise Panthers Basketball club are bringing back the exciting Duck Race in the Triogue river at 2pm.
The Lower Square will have bouncy castles and face painting, and the Ricky Lawless and Grainne Buggy schools of dancing will lead the crowds in some traditional Irish dancing at 2:15.
That will be followed by live bands on the street, and tea and coffee will be available from the PATH homeless charity on the street.
Wristbands and tea and coffee will be on sale in the old O’Loughlin’s chemist from 10:30am.
In the Dunamaise Arts Centre, Portlaoise sports clubs will give the public a chance to hone their skills, with ice-cream, treats, crafts and a Busking competition with a €100 prize on site.

The popular Tug of War is back again this year, while some of the parade participants will do displays.
