The schedule was set on Friday as soon as the Royal Gazette published the royal endorsement of Chuan as the house speaker and Suchart Tancharoen and Supachai Phosu as his deputies.
The Constitution does not set the deadline for the election of the head of the government but states that parliamentarians should be notified of the vote at least three days in advance, unless there is an emergency.
Both the Senate and the House of Representatives will vote together to determine the next PM.
Chuan said the notification letters would be sent to the parliamentarians on Saturday.
