Would phrases like these generally be considered inclusive of the current period?
I think it's pretty clear that last week does not include the current week. But does last 2 weeks include the current week? Does it make a difference where you currently are in the period?
For instance does last 2 weeks on Sunday mean the exact same time period as last 2 weeks on the following Monday (assuming you start a new week on Monday). On the following Thursday, does it then become an 11 day period rather than 14 days?
