Best Time to Meet: Shanghai, Réunion
We algorithmically calculated the optimal overlapping business hours to minimize sleep disruption for this group of 2.
The Intelligent Suggestion
The least disruptive meeting time is:
Algorithm Fairness Score: 100/100
We calculate overlapping windows by assigning a "pain penalty" to late night or early morning hours. Everyone is perfectly inside their 9-to-5 working window. Incredible!
How we find the best meeting time
We test every hour of the day (in UTC) and score each slot by how disruptive it would be for every participant. A 9:00 AM–5:00 PM local time gets a pain score of 0; a 7:00–9:00 AM or 5:00–9:00 PM slot gets a score of 2 (slightly annoying); anything between 9:00 PM and 7:00 AM gets a score of 10 (sleep disruption). The slot with the lowest total pain is the "best" time.
For the 2 cities you selected (Shanghai, Réunion), the time spread is 4 hours, which means standard 9-to-5 hours largely overlap in all cities.
Pairwise time gaps
- Shanghai ↔ Réunion: 4 hours apart, 5,669 miles.
Tips for scheduling across these cities
- Pick a recurring slot if your team meets regularly—rotating the time zone burden is fairer than fixing it on one group.
- Record meetings so anyone who had to attend at 6 AM or 11 PM can catch up async.
- Prefer written agendas when at least one participant is attending outside their normal working hours.
- Use the visual planner below to drag-select a slot and share a read-only link with participants.
