Best Hours to Schedule Los Angeles–Tokyo Calls
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.
| When | Los Angeles | Tokyo | Fit |
|---|---|---|---|
| PST → JST (UTC-8 to UTC+9, while Los Angeles is on PST) | 4:00 PM–5:00 PM | 9:00 AM–10:00 AM (next day) | Both inside 9 AM–5 PMWinter: the only hour where both 9-to-5 days overlap. |
| PDT → JST (UTC-7 to UTC+9, while Los Angeles is on PDT) | 5:00 PM–6:00 PM | 9:00 AM–10:00 AM (next day) | 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.
About Los Angeles (PT)
Los Angeles uses PST (UTC-8) in winter and PDT (UTC-7) from the second Sunday in March to the first Sunday in November. Tokyo doesn't change, so the gap narrows by an hour in summer. 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.
About Tokyo (JST)
Tokyo uses JST (UTC+9) all year. A Tokyo morning is the previous afternoon in Los Angeles, so Tokyo is the side that has to accept the date difference. 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.
How to Avoid Los Angeles–Tokyo Conversion Mistakes
Tokyo is already on the next calendar day from these PT times onward: 7:00 AM for PST → JST, 8:00 AM for PDT → JST. For example, 11:00 PM PT is 4:00 PM in Tokyo on the next day (PST → JST).
Dates cause more trouble here than 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, and remember the gap is an hour smaller in summer.
