What time is it in Japan if its 10:00 pm in San Diego, California, U.S.A.?
In summer, when it’s 10:00 pm in San Diego, it’s 2:00 pm the next day in Japan. In winter, when it’s 10:00 pm in San Diego, it’s 3:00 pm the next day in Japan. Japan Standard Time is nine hours ahead of Greenwich Mean Time. Unlike the United States, Europe, and many other countries, however, Japan does not use Daylight Saving Time, so the time difference with those countries gets one hour shorter in summer. Confused? Well, recently the Japanese government has been thinking of introducing DST. That would make the time difference the same all year round.
