The meeting planner highlights the hours that overlap for everyone.
How does daylight saving affect JST to AKDT?
The labels JST and AKDT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
Why can you trust this JST to AKDT converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so JST to AKDT stays accurate for today and for any past or future date you type in.

Do JST or AKDT use daylight saving time?
Japan Standard Time (JST) is a fixed offset with no daylight saving; Alaska Daylight Time (AKDT) observes daylight saving, alternating with AKST.
Why might the real-world JST–AKDT difference change during the year?
The labels JST and AKDT are fixed offsets, so this converter is always exact. But Alaska Daylight Time's region switches between standard and summer time, so for part of the year you may actually want JST to AKST. Always check which label a region is currently using before you schedule.
