While many used the “snowpocalypse” as an excuse to raid the bread aisle and spend the weekend on the couch watching movies, not everyone took the day off.

From October 1st to March 31st, the guard is changed every hour, on the hour in a ritual that includes a salute to the Unknown who have been “symbolically given the Medal of Honor.”

The tomb is guarded by soldiers from the 3rd U.S. Infantry Regiment (The Old Guard). Their standard of conduct is outlined in The Sentinel’s Creed. Part of their creed reads:

My dedication to this sacred duty

is total and whole-hearted.

And with dignity and perseverance

my standard will remain perfection.

After March 31st, the honorable ceremony can be witnessed twice as often since the guard change is conducted every half hour, and the cemetery remains open for an extra two hours.
