The Certification of the 2020 US Election Results is on Schedule. Here’s a Timeline.

Monday is also the deadline for counties in Pennsylvania to certify their totals and send them to Kathy Boockvar, the secretary of the commonwealth, who will certify the state results. Pennsylvania doesn’t have a hard deadline for when Ms. Boockvar must sign off, but there is no reason to expect a delay.

Maine also has its certification deadline on Nov. 23, too, but there are no serious disputes there.

This is the certification deadline for Minnesota, North Carolina and Ohio, none of which are expected to be contentious. Mr. Biden won Minnesota; Mr. Trump won North Carolina and Ohio.

Arizona has to certify its results by this date, as do Iowa and Nebraska. Mr. Biden won Arizona, Mr. Trump won Iowa, and in Nebraska, Mr. Trump won statewide but Mr. Biden won one electoral vote in the state’s Second Congressional District.

The Arizona Republican Party is trying to delay certification, pressuring county officials and asking a court to postpone certification in Maricopa County, which includes Phoenix.

But in the absence of a court order — and, so far, the courts have rejected almost every Republican challenge across the country — counties are expected to certify on time and Katie Hobbs, the secretary of state and a Democrat, is expected to sign off on the final, statewide certification.

No disputes are expected in Iowa or Nebraska that could delay certification.

This is the deadline for Nevada and Wisconsin, both of which Mr. Biden won, to certify their results.

In Nevada, the first step is for county commissioners to certify the results and send them to the secretary of state, who will present summaries to the Nevada Supreme Court. Ultimately, the governor will need to confirm the outcome. The Trump campaign has filed a lawsuit baselessly claiming that Mr. Trump actually won Nevada, and conservative groups are trying to nullify the results, but these claims are highly unlikely to lead anywhere.
