Paris ↔ Tbilisi

Paris and Tbilisi sit two hours apart, with Paris behind. The shared focus block runs from 09:00 to 15:00 Paris time — a six-hour window that comfortably covers a full morning and early afternoon on both sides. Live collaboration is realistic: both cities operate on a standard Monday–Friday workweek and share enough of the business day that decisions can land inside the same working cycle. The primary scheduling tension is not the offset itself but the lunch band, which in Paris can run long and in Tbilisi tends to compress the early afternoon. A recurring slot anchored in the late-morning or early-afternoon range avoids both the lunch drag and the start-of-day capacity gap.

The overlap band is 09:00 to 15:00 Paris time (11:00 to 17:00 Tbilisi time). Paris carries the earlier-side burden: scheduling a call before 10:00 Paris means Tbilisi is already deep into its morning. Tbilisi carries the afternoon burden: a call after 14:00 Paris puts Tbilisi into the early evening. Both cities face a mild lunch conflict that can chip into the overlap if meetings run long. Because this pair carries a DST fragility flag, recurring slots need a twice-yearly review: when Paris shifts its clocks for European Summer Time, the effective window between the two cities compresses by one hour until Tbilisi makes its own seasonal adjustment.

Best window: 10:00–12:00 Paris / 12:00–14:00 Tbilisi on weekdays. Alternative slot: 14:00–15:00 Paris / 16:00–17:00 Tbilisi — use this only when the morning band is unavailable, and watch for lunch-runover risk in Paris. Avoid: Calls before 09:00 Paris (Tbilisi is not yet at full capacity) and after 15:00 Paris (Tbilisi is winding down). If you run a weekly recurring call, treat the DST shift weeks as review moments rather than automatic carries — the one-hour compression changes who is most burdened that week.
