The week grid and call windows were worked out for 11 Jan to 17 Jan 2027 with the IANA time-zone rules for Europe/Berlin (Ramstein) and America/Chicago (San Antonio). That week both places are on standard time. The table uses the same rules for every day of 2027. The finder above recalculates for the current week in your browser.

Wednesday times. Send times as “your 8 pm” or “my 8 pm” so nobody has to guess whose clock you mean.
If one of you is deployed or stationed in Ramstein
Duty days rarely follow nine to five. Set the work hours on the Ramstein 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
The Long Goodbye keeps your person’s local time and time of day on your home-screen widget and lock screen, so you can see whether it is morning coffee or midnight in Ramstein before you call. A “thinking of you” tap lights up their widget, and a countdown keeps the next visit in view.
What is the time difference between Ramstein and San Antonio?
Ramstein is 7 hours ahead of San Antonio for most of the year. Because the two places change their clocks on different dates, the gap is 6 hours from 14 March to 27 March and from 31 October to 6 November 2027.
What is the best time to call Ramstein from San Antonio?
In January, the easiest two hours on a weekday are noon – 2 pm San Antonio, which is 7 – 9 pm Ramstein: San Antonio lunchtime, Ramstein evening, during San Antonio’s lunch break. At the weekend, Sat 11 am – 2 pm San Antonio (Sat 6 – 9 pm Ramstein) gives you a longer call. Change the awake and work hours in the finder on this page to fit your own days.
How many waking hours do Ramstein and San Antonio share?
If both of you are awake from 7 am to 11 pm, you share 9 hours on a January weekday, but none of them falls outside 9-to-5 working hours in both places.
Does daylight saving time change the call times?
Yes. In 2027 San Antonio changes its clocks on 14 March and 7 November and Ramstein changes its clocks on 28 March and 31 October, so a call you keep at the same time in San Antonio moves by an hour in Ramstein on those dates. Check the table on this page and agree the new time out loud after each change.
