Best Hours to Schedule India–Tokyo Calls
With 9-to-5 days on both sides, the shared window is 9:00 AM to 1:30 PM in India, which is 12:30 to 5:00 PM in Tokyo, 4 hours 30 minutes in all. Tokyo's 5 PM close (1:30 PM in India) ends it and India's 9 AM start (12:30 PM in Tokyo) opens it. Tokyo is already 3 hours 30 minutes into its day when India begins.
| When | India | Tokyo | Fit |
|---|---|---|---|
| IST → JST (UTC+5:30 to UTC+9, all year) | 9:00 AM–1:30 PM | 12:30 PM–5:00 PM | Both inside 9 AM–5 PMTokyo's 5 PM close ends it. |
"Inside 9 AM–5 PM" is a planning assumption for a standard office day on each side, not a claim about any company's hours.
About India (IST)
IST (UTC+5:30) never changes, and neither does Tokyo's time, so once you've learned the half hour this is one of the simplest conversions to get right.
About Tokyo (JST)
Tokyo uses Japan Standard Time (JST, UTC+9) for the whole country. Japan doesn't use daylight saving today, so JST is the same in January and July. Add 3 hours 30 minutes to any India time and you have the Tokyo time. To go the other way, subtract it: 9:00 AM in Tokyo is 5:30 AM in India.
How to Avoid India–Tokyo Conversion Mistakes
From 8:30 PM IST onward, Tokyo is already on the next calendar day. For example, 11:00 PM IST is 2:30 AM in Tokyo on the next day (IST → JST).
Dropping the half hour is the usual error. India to Tokyo is 3 hours 30 minutes, not 3 or 4, so 2:00 PM in India is 5:30 PM in Tokyo, not 5:00 or 6:00 PM. Because both zones are fixed, you can check any result with the same sum: India time plus 3 hours 30 minutes.
Worked Example: A Half-Day Workshop Between India and Tokyo
If you're planning a workshop for both teams, India's morning is the best option. A session from 9:30 AM to 1:30 PM in India runs 1:00 PM to 5:00 PM in Tokyo, a four-hour stretch that sits inside normal hours on both sides.
Starting earlier doesn't work for Tokyo. Tokyo's 9:00 AM is 5:30 AM in India, so an India-side attendee has to be online before 6:00 AM to join a Tokyo opening. Starting later runs out of Tokyo: a 2:00 PM start in India is 5:30 PM in Tokyo, which is after Tokyo's usual close.
Both countries stay on fixed time all year, so the 3 hour 30 minute gap holds in every month. The half hour is the only thing you need to double-check, since :00 times in India become :30 in Tokyo.
