Creates Thu-out / Mon-back tentative flights for the traveler each week, alternating host. Existing tentative flights in the range are replaced; booked flights are kept.

For a long trip, clear flights so each person just holds their last location. Add the outbound/return flights to the trip destination separately if you want them tracked.

Controls which months the calendar displays. This is just the view window — your flights, trips, and notes are never affected.
