Orvil,

I just reread your question. You have no obligation to check your schedule on the 31st since you are on an X day on the 1st. Save your golden days for later in the month.

You only check your schedule/acknowledge SC/trip after 1500 the day prior to your first on call day, and no later than 1 hour prior to a SC or 3 hours prior to report for a rotation.
