Los Angeles to Tokyo Time Converter
Tokyo is 17 hours ahead of Los Angeles on PST and 16 hours ahead during PDT, so Tokyo is always on the next calendar day for a Los Angeles morning. 9:00 AM in Los Angeles is 2:00 AM the next day in Tokyo on PST and 1:00 AM the next day on PDT.
The Date Line Does More Damage Than the Hours
A call at 4:00 PM on a Monday in Los Angeles is 9:00 AM the next day in Tokyo on PST, which is Tuesday morning there, so a Monday deadline in Tokyo and a Monday deadline in Los Angeles aren't the same moment. Write both dates in the invite.
A Los Angeles morning is deeper into the next day: 9:00 AM is 2:00 AM the next day in Tokyo on PST and 1:00 AM the next day on PDT. Reading it the other way, 9:00 AM in Tokyo is 4:00 PM the previous day in Los Angeles on PST and 5:00 PM the previous day on PDT, always the day before.
How the Gap Moves Through the Year
Tokyo doesn't change its clocks, so the only change comes from Los Angeles.
| Stretch | Tokyo is ahead by |

| First Sunday in November to second Sunday in March (PST) | 17 hours |
| Second Sunday in March to first Sunday in November (PDT) | 16 hours |
8:00 AM in Los Angeles is 1:00 AM the next day in Tokyo on PST and 12:00 AM the next day on PDT.

The One Hour Both Days Share
The two working days barely meet, and the overlap is at the end of the Los Angeles day. On PST, 4:00 to 5:00 PM in Los Angeles is 9:00 AM to 10:00 AM the next day in Tokyo, one hour inside both days. On PDT the gap is 16 hours, so 5:00 PM in Los Angeles is only 9:00 AM the next day in Tokyo, just as Tokyo opens. The shared hour then needs Los Angeles to stay on late: 5:00 to 6:00 PM there is 9:00 AM to 10:00 AM the next day in Tokyo.
| Los Angeles | Tokyo |
|---|---|
| 4:00 PM–5:00 PM | 9:00 AM–10:00 AMnext day |
| PST → JST: Both inside 9 AM–5 PM Winter: the only hour where both 9-to-5 days overlap. | |
| 5:00 PM–6:00 PM | 9:00 AM–10:00 AMnext day |
| PDT → JST: Los Angeles: after 5 PM. Tokyo: inside 9 AM–5 PM. Summer: Los Angeles has to stay an hour past 5 PM. | |
"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.
If Tokyo Hosts
From the Tokyo side the same hour is the start of the morning. 9:00 AM in Tokyo is 4:00 PM the previous day in Los Angeles on PST and 10:00 AM is 5:00 PM the previous day. A Tokyo team that starts at 8:00 AM reaches Los Angeles at 3:00 PM the previous day on PST and 4:00 PM the previous day on PDT.
