The current difference

Right now it is 5:38 AM Friday in Sao Paulo and 5:38 PM Friday in Tokyo (JST). Tokyo (JST) is 12 hours ahead of Sao Paulo, which means the time there is on the same day. The offsets are read live: Sao Paulo is on standard time and Tokyo (JST) is on standard time, and the gap can change when either region changes its clocks.

Scheduling calls and meetings

The table converts common hours from Sao Paulo to Tokyo (JST). If you work in Sao Paulo and need to meet colleagues in Tokyo (JST), the two 9-to-5 working days do not overlap, so one side will need an early start or a late finish. Where the gap is large, rotate the inconvenient time between the two teams.

Why zone differences shift

Many regions add an hour in summer, but the dates differ: the United States and Canada change on the second Sunday of March and the first Sunday of November, Europe on the last Sundays of March and October, and countries such as Pakistan, India, Japan, Singapore and the Gulf states do not change at all. For that reason the difference between two zones is not always the same number of hours all year.

Using the converter

Choose another pair from the boxes above or from the links below. The page recalculates from the current UTC offsets each time it loads, so the answer is right today and stays right after the next clock change.

Today's date at a glance

Today is Friday, October 2, 2026. That is day 275 of 365 in 2026, in ISO week 40, with 90 days to go before the year ends. The next dates people plan around are Diwali on Saturday, October 10; Columbus Day on Monday, October 12; Halloween on Saturday, October 31. The moon is a Waning Gibbous tonight, with about 66% of its face lit. All of these figures are recalculated when the page loads, so they always describe the day you open it, not the day the page was published.

How the calendar works

The Gregorian calendar has twelve months of 28 to 31 days. A normal year has 365 days and a leap year has 366, with the extra day added to February in every year divisible by four except century years that are not divisible by 400. Because 365 is one more than 52 weeks, most dates move forward one weekday each year and two after a leap day. Weeks are numbered under ISO 8601, which starts weeks on Monday and gives week 1 to the week containing the first Thursday of January.
