These windows give both sides a normal daytime or evening hour, between 8 AM and about 9:30 PM. They are for a regular weekday.
- Tokyo: Start the call between 8 AM and 5 PM India time (11:30 AM to 8:30 PM in Tokyo).
For a work call, the best window is the Indian morning and early afternoon, which is the Japanese afternoon and evening. A call at 9 AM in India is 12:30 PM in Tokyo. Late in the day in India is already night in Japan.
Common mistakes with the India to Japan time difference
- Adding a seasonal change. There is none. Japan is 3 hours 30 minutes ahead of India in every month.
- Subtracting instead of adding. Japan is ahead of India, so add 3 hours 30 minutes to the Indian time.
- Mixing up flight times. Flight tickets show local time at each airport. A flight that leaves India at night can land in Japan the next morning, so check both dates.
