Less than two weeks ago, President Trump warned he'd shut down the U.S. Government if he didn't get $5 billion for his border wall with Mexico in the new budget.
Democrats called his bluff; Trump didn't blink. And so, a partial shutdown began at midnight.
So, what does it mean in practical terms to have a partial shutdown, which Trump himself predicted could go on for a "very long time?"
1. About 75 percent of the government stays open.
Let's start with the fact that it's just a "partial" shutdown. There are some agencies that will be hit much harder than others, but most of the truly essential functions of government will continue.
Among these, the Department of Defense, the Department of Veterans Affairs, and the Department of Health and Human Services are already funded through 2019, so they shouldn't be affected.
2. But about 38 percent of employees will be hit.
There are 2.1 million federal employees. Of them, about 400,000 will be sent home without pay, and another 400,000 will be required to come to work, but won't be paid.
Some of the affected departments here include Homeland Security, Justice, State, Transportation, and Treasury. As an example, all 60,000 employees of the Customs and Border Protection would be required to go to work without pay.
This also includes Transportation Security Administration officials -- so airports should remain open and more or less unaffected. It also includes the Border Patrol -- ironic, since Border Patrol officers will have to work without pay, in a dispute over funding a border wall.
Also, "air-traffic controllers, prison guards, weather-service forecasters and food-safety inspectors, and would continue coming to work. Federal Bureau of Investigation agents, Forest Service firefighters" have to work, according to the Journal.
3. The National Parks stay open
This is interesting -- in earlier shutdowns, the spectacle of National Parks closing became big symbols of government ineptitude in a shutdown. But this time, the Parks Service is keeping most of its facilities open, even as about 80 percent of its employees will be furloughed.
On the National Mall for example, you'll still be able to tour the monuments, but there won't be Park Rangers available to offer information and assistance. The Smithsonian museums will remain open, too-- at least through Jan. 1.
4. It's a good time to cheat on your taxes.
That's because nine out of 10 IRS employees will be furloughed, so far fewer audits and return exams. That also means less chance of being able to call the IRS to ask for help on a tax issue.
5. The Mueller investigation continues.
About 85 percent of Justice Department employees still have to go to work, even if they don't get paid. The special counsel investigating possible collusion with Russia in the 2016 election however, will continue apace. That office's funding is guaranteed.
6. You can get your passport (probably) and the mail will still be delivered.
Passports should continue to be issued although timing might be affected. (Interestingly for me anyway, I knew that because I wrote about the government shutdown in 2013 for Inc.)
The Postal Service basically continues unaffected too, "because the Postal Service funds its operations through its own sales rather than tax dollars."
7. We sort of get a four-day repreive.
The shutdown began at midnight on Saturday December 22, which also happens to be the first of a four-day weekend for the government, since next Tuesday is Christmas.
All of which means that many of the 800,000 employees who won't be paid, weren't planning to work anyway the next four days. (In most past shutdowns, they ultimately got back pay when the government reopened.)
So, next Wednesday is that day when people will really start to notice -- and then, if it lasts long enough, into the day after New Year's Day.
8. Weirdly, many workers have to come in, only to be told to go home.
Acording to the Post: Some will have to -- briefly, anyway.
"This is what's known as an "orderly shutdown," during which employees who are furloughed can be allowed up to come in for up to four hours to preserve their work, finish timecards or turn in their government-issued phones. ... What can we tell you? The federal government is a quirky enterprise."
9. Meat will be okay
At the Agriculture Department, the government will still inspect meat and other food. And support programs like food stamps will keep going.
10. Sandwiches will be free.
This is mostly for Washington DC area employees anyway, but if they're affected by the shutdown, celebrity chef Jose Andres says his restaurants will offer free lunch sandwiches.
