Tokyo and Toronto share no standard 9–5 working hours; the least disruptive option is 9:00 AM GMT+9 (8:00 PM EDT).

Tokyo and Toronto are 13h apart. When it's 9 AM in Toronto, it's already 10:00 PM in Tokyo — meaning Tokyo's working day is well underway before Toronto's morning has properly started.
There is no overlap during standard 9–17 business hours. Every synchronous meeting requires someone to work outside normal hours. The fairest approach is to rotate that burden: one week Tokyo takes the early call, the next week Toronto does. TimeSync's standup planner computes the exact rotation automatically.
Recurring calendar invites for Tokyo–Toronto meetings need a DST audit every year. If one city's clocks change before the other's, there's a window — sometimes three weeks, sometimes five — where the same calendar slot lands an hour earlier or later than intended. Always schedule with explicit timezone labels, not just clock times.
For truly zero-overlap pairs, the most important investment is async infrastructure: a written daily digest each team can read at the start of their day, a shared decision log so nothing critical gets blocked waiting for a live reply, and a clear escalation path for genuine emergencies. With those in place, most distributed teams find they need far fewer live calls than they assumed.
Tokyo is UTC+9 and Toronto is UTC-4, a difference of 13h. This gap may shift by 1 hour during DST transitions.
There is no overlap during standard 9–17 hours. Consider a rotating schedule or an early/late meeting. TimeSync's standup planner can find the least-painful slot.
Yes, partially. Toronto observes daylight saving time; Tokyo does not. Toronto's clocks change around March 8 and November 1, shifting the gap between the two cities by 1 hour for part of the year.
Tokyo and Toronto have no overlap during standard 9 AM–5 PM business hours.
Under standard 9–5 schedules, no. The 13h gap means the two cities' business days do not overlap. Teams that need synchronous collaboration typically shift one side's hours, rotate the inconvenient slot fairly, or rely on async-first workflows with structured handoffs.
