I admit my errors, the 48 hour was memory of my previous company.
The premise is still the same, and the exact wording:
Daily open time pot shall until 1200 EST/EDT contain all known open flying and R days beyond the next calendar day.
Example: Daily Open time available for Wednesday and beyond will remain in open time until Monday at 12:00 EST/EDT.
So I suppose if you want to be accurate, it’s not 2 full calendar days, but a 36 hour blackout from noon eastern to 00:01 the third day.
