If one of you is deployed or stationed in Grafenwöhr
Duty days rarely follow nine to five. Set the work hours on the Grafenwöhr side to “No fixed work hours” and read the grid as a map of who is likely awake, not a promise of who is free. Calls may depend on access and schedules you cannot see from home, so keep the windows above as a starting point rather than a plan.
Follow your unit’s guidance on what you share about times, places and movements. The deployment countdown has a private mode that hides every date, and the deployment countdown guide covers OPSEC habits for families.
Stop doing the math every day
