With a start date for your project in A2

=NETWORKDAYS(A2,NOW())

will return how many weekdays your project has been running for.

With the planned end date in B2

=NETWORKDAYS(NOW(),B2)

Will return the number of days remaining. Note that this last formula will
go negative if your project overruns

projects, to check how many days does the project has or left.
