Best time to call Tokyo from Mumbai (and vice versa)

The window in which both cities are inside their 9:00–17:00 working day runs from 09:00 to 13:30 in Mumbai, which is 12:30 to 17:00 in Tokyo: 4.5 hours of overlap per day. For a call that disturbs nobody, aim for the middle of that window.

Outside that window, the practical rule: mornings in Tokyo are afternoons in Mumbai. Avoid any hour that falls before 8:00 or after 21:00 in either city.

Looking for it the other way round? This page covers both directions: Tokyo to Mumbai is the same difference with the sign flipped.

The two time zones

Mumbai — Asia/Kolkata

Mumbai, like all of India, uses India Standard Time (IST), a fixed UTC+5:30. The half-hour offset and the absence of daylight saving make Indian conversions the most error-prone in remote teams.

Tokyo — Asia/Tokyo

Tokyo keeps Japan Standard Time (JST), a fixed UTC+9 with no daylight saving. Japan and South Korea share the offset, so Tokyo and Seoul are always on the same clock.
