First, SharePoint wildcard filtering [Today] compares only dates, not times. As far as I know, there is no way to compare time in the web interface.
Assuming "TimeOver" is the deadline for your project, and "Start" is when the project begins ...
Add something to the list when it is expired, saying: TimeOver is less than [Today]
Add something to the list when it was launched today: Start is [Today]
Add something that was created in the last week: Start more than [Today] -7
Add something to the list that should be sent within 30 days: TimeOver is longer than [Today], and TimeOver is less than [Today] +30
