How much shared working time do 61 business corridors actually have?

We measured the 9-to-5 overlap for every city pair in the planner on a representative weekday. The results show which routes are genuinely easy and which only work with a bridge slot.

Methodology

For each of the 61 city pairs, we defined a 09:00–17:00 working window in both cities and computed the minute-by-minute intersection for Monday, June 15, 2026. Conversions use the IANA Time Zone Database through the same engine that powers the planner. A pair with a score of zero has no moment when both cities are inside 9-to-5 under standard hours.

This is a snapshot, not a verdict. Teams with shifted hours, four-day weeks, or a willingness to take a bridge slot can create overlap where the default schedule shows none. The date matters too: June is northern summer and southern winter, so a January run would move several scores by an hour.
