Practical scheduling tips & travel notes
Watch the half-hour offset
Tokyo is 3 hours 30 minutes ahead of Mumbai (Asia/Kolkata → Asia/Tokyo). That half-hour makes whole-hour assumptions wrong — always verify with the tool.
Best meeting windows
Aim for late morning Mumbai (10:00–12:00 IST) which maps to early–mid afternoon in Tokyo (13:30–15:30 JST) — a practical overlap for synchronous work.
Early Tokyo = very early Mumbai
A 09:00 JST meeting equals 05:30 IST. Avoid scheduling Tokyo mornings if Mumbai participants prefer not to join before dawn.
Travel tip for eastward trips
A 3½-hour eastward jump can affect sleep. Shift sleep/wake times by 1–2 hours in the days before departure and use the Jet Lag Planner for targeted advice.
Calendar invite sanity
Because of the 30-minute offset, double-check calendar invites and time-zone tags so recipients in both cities see the correct local time.
