Timezone Overlap Calculator

Map your team's working hours across time zones. See where you overlap, where you don't, and how long context has to survive the gap.

Your team's locations

Add the cities where your team works. We'll calculate the overlap.

What this means

Your team has zero shared working hours. Every handoff requires someone to reconstruct context from written artifacts alone. Without structured handoffs, decisions made in one shift will be invisible to the next — and work will be blocked until someone wakes up.

You've measured the overlap. Two steps left:

  1. Map timezone overlap ✓ Map timezone overlap
  2. Estimate the annual cost of those gaps
  3. Replace the gaps with structured 60-second handoffs

Now put a number on it
Put a dollar figure on the coordination gap across your 2 locations.

Overlap tells you when. Not whether context survives.

Shared hours let your team sync. StandIn makes sure what they decided stays on the record after they log off — so the next shift starts executing, not reconstructing.
