The event will culminate in the cutting of a ribbon and the stadium being declared formally open.
The very first game played at Ravenhill was Ulster v Leinster on January 12, 1924.
Three new stands, funded by an investment by DCAL of almost £16 million, have been built at the ground as part of the redevelopment.
The stadium will host the Heineken Cup quarter-final between Ulster and Saracens on Saturday, April 5. Following that game further fit-out work will be carried out on the Grandstand ahead of the official May opening.
Work on the new Nevin Spence Centre, an education and heritage centre, based in the new Memorial End Stand, a new community 3G pitch facility and other improvements will start in the summer.
Commenting on the opening, Ulster Rugby Chief Executive Shane Logan said: "The new Ravenhill Stadium is a world class stadium and a state of the art home for all of rugby in Ulster.
"We have some exciting plans for the opening and I have no doubt that it will truly be a once in a lifetime event for any Ulster fan."
