ANC is open every day of the year. Just went by there today... Additionall, the hours are posted on the ANC website. I recommend that you download the app, and you can see all of this information and so much more.
Guess you should check a bit more carefully... As they are open.
Arlington National Cemetery is open 365 days a year. We are open from 8 a.m.-7 p.m. every day from April-September, and 8 a.m.-5 p.m. every day from October-March.
It should be open
