The clock is ticking once again.

Congress has to pass a spending bill by Feb. 8 to keep the government open through March 23.

Republican and Democratic Senators announced a two-year budget agreement Wednesday that includes an increase in military spending, an extension for the Children’s Health Insurance Program and additional funds for disaster relief, among other issues.

"I am pleased to announce that our bipartisan, bicameral negotiations on defense spending and other priorities have yielded a significant agreement," Senate Majority Leader Mitch McConnell, R-Ky, said in a speech on the House floor.

It's a deal "neither side loves, but both sides can be proud of," Senate Minority Leader Schumer, D-N.Y., added.

But Schumer doesn't speak on behalf of all Democratic lawmakers, according to Minority Leader Nancy Pelosi, D-Ca. Pelosi held the floor of the House of Representatives for more than eight hours Wednesday, in a record-breaking marathon speech protesting the budget deal, which does not address immigration.

"This morning, we took a measure of our Caucus because the package does nothing to advance bipartisan legislation to protect Dreamers in the House," said Pelosi, as she shared the stories of "Dreamers" on the House floor. "Without a commitment from Speaker Ryan comparable to the commitment from Leader McConnell, this package does not have my support."

Disagreements over the Deferred Action for Childhood Arrivals (DACA), an Obama-era program that protects the nearly 800,000 undocumented people who were brought into the U.S. as minors, led to a three-day government shutdown on Jan 20.

Fox News asked Marc Goldwein, senior policy director of the Committee for a Responsible Federal Budget – a bipartisan, nonprofit organization that educates the public on fiscal policy issues – to explain a government shutdown, and he answered seven basic questions about the process that Americans should know.

What causes a government shutdown?

A shutdown occurs when Congress and the president fail to sign into law 12 appropriations bills (which determine spending for specific government agencies) in order to continue providing funding for government operations.

How can you prevent a government shutdown?

To avoid a shutdown, members of Congress can give themselves an extension, known as a continuing resolution (CR). The temporary funding measure keeps the federal government open and allows lawmakers more time to negotiate the remaining appropriations bills.

“The bar for a CR is pretty low. You’re not agreeing to anything new politically; it’s a no-brainer,” Goldwein told Fox News.

That’s exactly how the government has been operating since Oct. 1.

Funding has been extended three times since then. The House and Senate approved a temporary spending bill on Jan 22, and Trump signed the measure to keep the government funded through Feb. 8.

How long does a government shutdown last?

As long as it takes. Congressional leaders from both parties have to reach an agreement to fund the government.

It usually takes a weekend for this to happen.

“We’re talking days or weeks – not months,” Goldwein said.

The federal government would be forced to shut down “nonessential services." Who would be affected?

"Essential staff at top level agencies would continue working, but most federal employees whose jobs aren’t vital would likely be sent home," Goldwein said.

For example, those who work at national parks, monuments and museums would be told to go home. 

"It doesn’t feel awesome to be told you’re not an essential employee. It's a little demoralizing to go home because you’re not important," Goldwein added.

In the 2013 shutdown, roughly 850,000 employees were furloughed per day, according to the Office of Management and Budget.

But not everyone is required to take unpaid leave.

The president, presidential appointees and members of Congress are exempt. The Postal Service, the TSA and Air Traffic Control will also continue business as usual.

Americans will still be able to get their Social Security and Medicare benefits and food stamps. However, people expecting VA benefits, unemployment benefits, farm subsidies and tax refunds may experience delays.

Do federal employees still get paid?

Most likely. The problem: They're not sure when they'll get their money. 

"Everyone loses from the government shutdown. An employee loses their paycheck at the time he or she needs it," Goldwein said. "Ultimately, we’re going to fund it anyway. It’s kind of silly."

Federal employees typically receive back pay shortly upon their return, though, Goldwein says, nothing is certain. Every agency has their own contingency plan in the event of a shutdown.

How many times has the government shut down?

The government has shut down 19 times since 1976, the year Congress introduced the Congressional Budget and Impoundment Control Act, according to the Committee for a Responsible Federal Budget’s research. Half of the shutdowns occurred over a weekend.

“Before 1980, the government didn’t really shut down,” Goldwein explained. “A lot of others were over the course of weekends. I call them ‘fake shutdowns.’”

Goldwein says there have really only been three significant government shutdowns in the history of the U.S.

Two occurred during the Clinton administration in the winter of 1995 to 1996. Former President Bill Clinton and the Republican Congress were at odds and shut the government down for a total of 26 days, Goldwein said.

The third occurred during the Obama administration in 2013, when a stalemate between the House and Senate led to a 16-day hiatus.

How much money can the country lose during a shutdown?

The 16-day government shutdown in 2013 cost the country $24 billion of lost economic activity, according to an analysis from ratings agency Standard & Poor's

"The payroll cost of furloughed employee salaries alone – that is, the lost productivity of furloughed workers – was $2.0 billion," the Office of Management and Budget reported in 2013.

Goldwein says shutdowns "waste money" more than they "cost money."

"We’re not going to spend more money. We’re just going to spend it on worse stuff," he explained. "Instead of paying employees to work, we’re paying them not to work."

“This is not a time to play politics,”  House Majority Leader Kevin McCarthy, R-Calif. added Wednesday, suggesting that Democratic leaders are telling members not to support a GOP temporary spending plan that would fund the government through Feb. 16.
