It's the overlap that a family manages, not the distance
Two clock dials eight hours apart leave one narrow band where both households are awake — the width of that band, not the miles between them, is what actually shapes a split family's calls.

Two clock dials, side by side on a charcoal tee. No numerals, just tick marks. The left dial sits eight hours behind the right, and each one carries a single narrow amber wedge running from centre to edge.
The wedges are the same width. That's the design.
What are two clock faces doing on a shirt about a family?
A pair of clock faces showing not the time in two places, but the one window when both are awake.
Each dial marks a household's day with tick marks only, no numbers — the actual hour doesn't matter to the design. What matters is the amber wedge, drawn to the same width on both dials, marking the hours when somebody on one side could plausibly call somebody on the other without waking them.
Why is the overlap the problem rather than the distance?
Because the miles between two households never wake anybody up, but a badly timed phone call does.
A family split across an ocean can still talk daily if their waking hours line up; a family an hour's drive apart but working opposite shifts can go a week without a real conversation. The mechanics are close to what any relationship stretched by geography already manages, except here the stretch is measured in hours rather than miles, and it's fixed by clocks rather than choice. The overlap is the number that actually decides whether a relationship runs on daily contact or has to save everything up for one call a week.
Do you need to ask anyone before you print this?
No — the design carries no names, no city, nothing that identifies either household beyond a gap in hours, so there's nobody to check with.
That changes the moment actual names or places get added instead of just the gap — at that point it becomes exactly the kind of record where asking first is worth doing, the same as any design built around a real, named relationship.
Why doesn't the overlap band stay a fixed width as the gap changes?
It doesn't — a bigger time difference generally narrows it, which is the whole reason the width is worth drawing at all.
Eight hours apart, if one household keeps ordinary waking hours, leaves a band of only a few hours where both are up — which is why the calls in a family like this tend to land at the same slightly odd hour every time, evening on one side and early morning on the other. Moving somewhere new changes a lot about a relationship; a time difference changes specifically this, and only this.
What does missing a call in that window actually cost?
A whole day, not an hour — because the band doesn't come back around until the following one.
Unlike a friend down the road, there's no dropping by later that afternoon. A missed window is a missed window until the same time tomorrow, which is also roughly why a family running on this schedule tends to treat a call at an unsociable hour as completely ordinary rather than an emergency — for one household it's the only slot there is.
Does each side experience the band the same way?
No — one household is finishing dinner and the other is barely awake, and the design doesn't try to pretend otherwise.
The two dials sit at different hours precisely so a viewer can see that: the same fifteen minutes on a call is the end of somebody's evening on one side and the very start of somebody's day on the other. Neither experience is the "real" one; the print just shows both without picking a home time zone to centre the design on.
Does this still work for a smaller gap, like two or three hours?
Yes, and the wedge just gets wider rather than the design changing shape.
A short gap leaves most of the day overlapping, so the amber band on both dials would run wide and the two dials would look almost like mirrors of each other. That's still an honest picture — it's a family for whom timing was never really the constraint, which is worth showing as clearly as the opposite case.
Does it print well?
Yes — two dials and a wedge are flat shapes with hard edges, which survives fabric well.
Keep the tick marks fine but not thread-thin, and the amber wedge solid rather than gradient-filled from light to dark — a soft fade across a shape this small goes muddy fast, while a flat wedge stays crisp wash after wash. Two dials side by side is naturally a wider composition, which suits a design built to run across more of the chest rather than one confined to a small centred badge.
How do I get one made?
Describe your own two time zones at JustOG — the gap in hours, and roughly when your overlap actually falls. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
