Oklahoma Legislature 2027: Bill Requests Due Dec. 4, Session Feb. 1

The Oklahoma Legislature’s bill request deadline is Friday, Dec. 4, 2026, and the First Regular Session of the 61st Legislature begins at noon Central Time (CT) on Monday, Feb. 1, 2027, according to the Oklahoma House of Representatives. The Oklahoma Senate’s 2027 calendar lists the same seven dates through sine die adjournment on Friday, May 28. All seven are in order with weekdays and times here, with a free printable tracker.

The House page carries a note: “Please note that only House Bills and House Joint Resolutions fall under these requests and filing deadline dates.” The Senate calendar lists no separate deadline of its own.

Oklahoma Legislature 2027 session dates

Both chambers publish the same list. The House calls it “Legislative Deadlines”; the Senate titles its page “2027 Legislative Calendar – 1st Regular Session of the 61st Legislature” (capitals lowered). Weekdays are computed from the dates. Times are Central Time as the calendars print them, with the Eastern Time (ET) equivalent: 12 noon CT is 1 p.m. ET, 4 p.m. CT is 5 p.m. ET and 5 p.m. CT is 6 p.m. ET.

Date	Weekday	Time	What the House and Senate calendars say
Dec. 4, 2026	Friday	none listed	“Bill Request Deadline”
Jan. 5, 2027	Tuesday	12 noon CT (1 p.m. ET)	“Organizational Day”
Jan. 14, 2027	Thursday	4 p.m. CT (5 p.m. ET), no later than	“Bill Introduction Deadline”
Feb. 1, 2027	Monday	12 noon CT (1 p.m. ET)	“First Day of the First Regular Session of the 61st Legislature” (Senate: “Session Begins”)
March 25, 2027	Thursday	none listed	“Third Reading Deadline for a Bill or Joint Resolution in the House of Origin”
May 6, 2027	Thursday	none listed	“Third Reading Deadline for a Bill or Joint Resolution for Opposite the House of Origin”
May 28, 2027	Friday	5 p.m. CT (6 p.m. ET), not later than	“Sine Die Adjournment”

The calendars give no time for Dec. 4, March 25 or May 6.

When does the Oklahoma session start in 2027?

Monday, Feb. 1, 2027 at 12 noon CT is the first day of the session. Organizational Day comes almost four weeks earlier, on Tuesday, Jan. 5 at 12 noon CT, and both chambers list it as its own entry. The two dates are separate lines on the House and Senate calendars, so Jan. 5 is not the opening of the session.

By our computation from the calendar, Feb. 1 is the first Monday in February and Jan. 5 is the first Tuesday after the first Monday in January. The pattern matches the calendar; the pages do not cite a rule for it.

What is the Oklahoma bill request deadline for 2027?

Friday, Dec. 4, 2026 is the “Bill Request Deadline.” The House says it applies to House bills and House joint resolutions. The Senate calendar lists the same date under the same label and does not describe it further. The next step is the bill introduction deadline, no later than 4:00 p.m. CT (5 p.m. ET) on Thursday, Jan. 14, 2027, which falls 18 days before the session opens.

Neither calendar gives a time of day for the Dec. 4 request deadline.

When does the Oklahoma Legislature adjourn in 2027?

The calendars set “Sine Die Adjournment” for not later than 5:00 p.m. CT on Friday, May 28, 2027. That is 116 days after the Feb. 1 opening, computed from the two dates. Before it, bills have two reading deadlines: Thursday, March 25 for a bill or joint resolution in its house of origin, and Thursday, May 6 for one in the opposite house.

How does the 2027 calendar compare with last year’s session end?

In 2025, the Oklahoma Senate said “The First Session of the 60th Oklahoma Legislature adjourned Sine Die today” in a press release dated May 30, 2025, a Friday. The 2027 calendar sets May 28, also a Friday and the last one in May. Both are first sessions of a Legislature, and the 2027 date is the calendar’s deadline, not a result.

Item	2025 (60th Legislature)	2027 (61st Legislature)
Sine die	Fri., May 30, 2025 (adjourned, per Senate release)	Fri., May 28, 2027, not later than 5 p.m. CT (calendar)
Start date	not in our sources	Mon., Feb. 1, 2027

How big are the two chambers?

The House of Representatives “consists of 101 members,” according to its website. The Oklahoma Senate home page describes the chamber as “48 Strong and Committed.”
