The Isis Adventure

I know I can only try 3 passwords per week. I was wondering if anyone knew if it was 3 attempts in a calendar week or if it was a rolling 7 day period. I have a 2 hour drive to the location so I tried 3 passwords at once last Tuesday. If it is a calendar week I can go today (my day off) and try again, but if it's a rolling week I will have to wait until tomorrow at the earliest, but I do not have any time for the rest of the week to make the trip.

Anyone know?
