Firing schedule?

Hi! Is there a schedule for when the kilns are being fired? I know it’s been about 2 weeks since the last glaze fire, and I’m working on some pieces that are on a timeline, so do the kilns just get fired whenever it is there a specific date that they are filled and fired?

@tonyreid or someone else can correct me, but I believe whenever the shelves are filled they’re fired.

They are fired when there is a load. The vent fan failed so we are a bit behind.
