An IFATC airport on the schedule is not active

I’m flying in to KIAD, which should be controlled, as it says in the schedule: March 16, IAD.
It’s not active. Just wondering. Thank You!
I would appreciate the controlling too:)

IFATC controllers are volunteers. It’s never a guarantee that all airports listed in the ATC schedule will be staffed at all times, as this depends on traffic demands and controller availability. The ATC schedule is simply guidance.


Thank you!!
