Eighteen-and-a-half months into their legislative cycle, and with less than three weeks to go, state lawmakers are running out of time.

Legislative leaders met Monday with Governor Charlie Baker and, with both major parties’ national conventions due to take place between now and the July 31 close of the session, acknowledged they are squeezed by the clock.

House Speaker Robert DeLeo, Democrat of Winthrop, said the loss of two weeks, when neither chamber will hold the types of formal sessions that allow them to advance major bills, “is something that concerns me.’’

“I wish we did have that time,’’ DeLeo told reporters.

Baker, a Republican, said he and the Democratic leaders in the Legislature discussed “the ‘big six’ items that are out there’’ during their regular Monday session. Those bills: a municipal modernization package; an energy omnibus; an economic development proposal; legislation imposing new regulations on ride-for-hire firms like Uber and Lyft; a gender pay equity bill; and a proposal to restrict noncompete agreements.

“Those are certainly the six items that I think we’re all focused on,’’ Baker said.

Lawmakers also intend to take up override votes for Baker’s vetoes to the state budget.

Baker also filed an amendment to that budget that would try to guarantee that illegal immigrants could not obtain driver’s licenses. Senate President Stanley C. Rosenberg said lawmakers were reviewing the language.

“We know we’ve got to get this resolved, and it was nobody’s intention that undocumented aliens would get access to driver’s licenses as a result of the bill,’’ Rosenberg said. “So we just need to make sure that the language is perfected, but we’re there in spirit and we need to get this resolved so we don’t run into problems with the federal government.’’
