Quick answers about converting between Tokyo and Lima. Can't find what you need? Email [email protected].

What is the time difference between Tokyo and Lima?
Tokyo is 14 hours ahead of Lima right now. We always show the live, daylight-saving-correct difference, so this figure already accounts for whichever side is observing summer time today.
When it's 4am in Tokyo, what time is it in Lima?

What's the best time for a call between Tokyo and Lima?
There's no comfortable 9-to-5 overlap between Tokyo and Lima — they sit on opposite sides of the planet's working day. Plan for an early or late call on one side, or hand work off asynchronously.
Does this account for daylight saving time?
Yes. We track every clock change in both places, so the abbreviations you see — JST and -05:00 — are the ones actually in effect right now, not a fixed all-year value. When either side changes its clocks, this page updates automatically.
Why is the date sometimes different on each side?
When two places are far enough apart, the same moment can fall on different calendar days. That is why some conversions are marked "previous day" or "next day" — it is the same instant in time, read off two clocks that crossed midnight at different points.
