What time is it in Buenos Aires when it's 9:00 AM in Tokyo?

Type 9:00 into the Tokyo field above and the converter shows the matching Buenos Aires time for today, daylight saving included. It also shows the Buenos Aires date in case the time crosses midnight.

Does this converter handle daylight saving between Tokyo and Buenos Aires?

Yes. It uses your browser's own time-zone data (Asia/Tokyo for Tokyo, America/Argentina/Buenos_Aires for Buenos Aires), which carries each region's daylight-saving rules, so the result stays correct all year.

Can it convert Buenos Aires time to Tokyo time as well?

Yes — press the swap button and the converter flips to show Buenos Aires → Tokyo, with the same live clocks and time picker.
