The opposition will be on the streets starting January 4 to protest Jubilee's "legal coup".
The mass action follows Thursday’s passing of amendments to the election laws by Jubilee MPs.
Cord says the amendments weaken electoral laws enabling election rigging and theft.
Raila Odinga and his Cord co-principal Kalonzo Musyoka on Friday said the demonstrations would be more intense than their weeks of anti-IEBC protests in May. However, the two said, the demos will be peaceful.
In the May protests at least six people were killed.
Cord stormed out of Parliament during the debate leaving Jubilee to pass the contentious amended electoral laws.
In the amendments, manual backup if electronic voter registration, identification and transmission systems fail on August 8, 2017.
The opposition has been adamant regarding the changes saying this will allow rigging.
Kalonzo and Raila said they had no choice but returning to the streets to protests against this legal coup.
“This is a legal coup. The Jubilee coalition has decided to deny Kenyans free and fair elections, just as it happened in Burundi,” said Raila from his Capitol Hill office.
The changes were to laws that Jubilee and Cord had negotiated with broad input and contributions from diplomats.
During an interview on Citizen TV on Wednesday, Deputy President William Ruto said the amendments were requested by the Independent Electoral and Boundaries Commission (IEBC).
Raila, quoted by the Star, said that Jubilee is breaking the law developed by experts.
He said Nigeria, Ghana, Namibia, Senegal and India have used technology in elections and Kenya cannot shy away from it.
“We cannot go to elections to participate in a fraud,” Raila said, accusing Deputy President William Ruto of being behind the "scheme".
