A new three-month legislative session will begin Sept. 8.
MLAs will return to Victoria on a Friday with a speech from the throne, with a new budget expected the following week.
MLAs will sit for 37 days until Nov. 30, with week-long breaks for Thanksgiving and Remembrance Day.
It will be the first legislative session that will test the governing deal between the BC NDP and Greens, a critical piece of the two parties' alliance and the NDP's minority government.
The two parties hold a combined 44 seats in the house, while the Liberals hold 42 following the resignation of former premier and party leader Christy Clark, who was defeated in a confidence vote in June.
Officials with the office of the premier were not immediately available for comment.
The NDP have already announced a number of initiatives in the lead up to the fall session, including a ban on the grizzly bear trophy hunt, raising the minimum wage 50 cents to $11.35 an hour, joining legal challenges against the Trans Mountain pipeline expansion, and scrapping fees for adult education and English language training.
Meanwhile, a BC Utilities Commission report on the financial implications of the Site C dam is expected Nov. 1.
The previous BC Liberal government cancelled plans for a 20-day fall legislative session in 2016. The legislature was in session for 26 days in fall 2015.
"I'm not sure why they want to go this long, unless they have a colossal amount of legislation they want to pass," Davies said.
The session will also take place during the middle of his party's leadership race to replace Clark, he added.
