California Legislature 2027-28 Session: Convenes Mon., Dec. 7

The California Legislature convenes its 2027-28 Regular Session at 12 noon on Monday, Dec. 7, 2026, according to the 2026 Tentative Legislative Calendar from the California State Senate and the Assembly Chief Clerk. The calendar, revised March 27, 2026, cites Article IV, Section 3(a) of the state constitution for the date. The 2027 calendar with bill deadlines is not posted yet, so the 2025 calendar is shown below for comparison.

Where the California Legislature stands from Nov. 30 to Jan. 1

Days count from today, Tuesday, Nov. 10, 2026. All rows come from the 2026 calendar.

Date	Days from Nov. 10	Calendar entry
Mon., Nov. 30, 2026	20	“Adjournment sine die at midnight (Art. IV, Sec. 3(a)).” This ends the 2025-26 session.
Mon., Dec. 7, 2026	27	“12 Noon convening of the 2027-28 Regular Session (Art. IV, Sec. 3(a)).”
Fri., Jan. 1, 2027	52	“Statutes take effect (Art. IV, Sec. 8(c)).”

The Senate events page said “No events are scheduled” on Nov. 10, 2026, so the Dec. 7 program, including any swearing-in order, is not announced. In 2024, CalChamber reported that “The California Legislature returns today for the start of the 2-year legislative session” on Monday, Dec. 2, 2024.

California 2027 bill deadlines: what is fixed and what is not

The 2027 calendar is not posted, so the bill introduction deadline, the house-of-origin deadline and the recess dates are unknown. Two budget dates are tied to the constitution sections the calendar cites and recur in the 2025 and 2026 calendars.

Item	Calendar wording	2027 weekday
Governor’s budget	“Jan. 10 Budget must be submitted by Governor (Art. IV, Sec. 12 (a)).”	Sunday, Jan. 10, 2027
Budget Bill passage	“June 15 Budget Bill must be passed by midnight (Art. IV, Sec. 12(c)(3)).”	Tuesday, June 15, 2027

Jan. 10, 2027 is a Sunday, and with no 2027 calendar there is no official note on that date.

What were the California Legislature’s 2025 first-year deadlines?

The 2025 calendar, revised Oct. 16, 2024, covers the first year of the 2025-26 session, the nearest comparison for 2027. Every date below is 2025, not 2027. “J.R.” means Joint Rule.

2025 date	Calendar entry
Mon., Jan. 6	“Legislature Reconvenes (J.R. 51(a)(1)).”
Fri., Jan. 10	“Budget must be submitted by Governor (Art. IV, Sec. 12(a)).”
Fri., Feb. 21	“Last day for bills to be introduced (J.R. 61(a)(1), (J.R. 54(a))).”
Fri., June 6	“Last day for each house to pass bills introduced in that house (J.R. 61(a)(8)).”
Sun., June 15	“Budget Bill must be passed by midnight (Art. IV, Sec. 12(c)(3)).”
Fri., July 18	“Last day for policy committees to meet and report bills (J.R. 61(a)(10)).”
Fri., Sept. 12	“Last day for each house to pass bills (J.R. 61(a)(14)).”
Sun., Oct. 12	“Last day for Governor to sign or veto bills passed by the Legislature on or before Sept. 12 and in the Governor’s possession after Sept. 12 (Art. IV, Sec.10(b)(1)).”

The 2026 calendar, the second year of that session, lists Monday, Aug. 31, 2026 as the “Last day for each house to pass bills” and Wednesday, Sept. 30, 2026 as the last day for the Governor to sign or veto bills passed before Sept. 1. The 2026 calendar also carries the footnote “*Holiday schedule subject to Senate Rules committee approval.”
