Please HELP: 7 staright day work checker

[gother]

Good Day!

Please help me on how to create an excel formula that will check if an employee will render 7 day straight working days in 2 consecutive weeks. Please see sample below.

The week starts on a Monday shift
The condition holds TRUE if the schedule of an employee will have more than 6 straight work days between week 1 and week 2.
