What to know about Jimmy Carter's funeral, national day of mourning

Between the lines: The funeral isn't open to the public, but you can watch the cathedral's live stream via YouTube.

Zoom in: Here's what closed to honor the longest-living former president:

• All federal agencies and offices, except for personnel who can't be excused for reasons of national security, defense or other essential services.
• The U.S. Postal Service is closing all post offices and suspending regular mail delivery. Operations resume Friday. UPS, FedEx and other pickup/delivery services aren't impacted.
• Financial markets (the New York Stock Exchange and Nasdaq). Banks aren't ordered to close, but check with your local institution.

Meanwhile, streets around the cathedral will be closed to cars from midnight to 3pm Thursday. Others will be open to only local traffic. See a full list.

What else is happening: U.S. flags will fly at half-staff on all federal buildings, grounds and naval vessels until Jan. 28 (including for inauguration).
