When it is 09:00 in Zurich it is 05:00 in São Paulo in January and 04:00 in July. São Paulo is 4 hours behind Zurich right now — but it is not constant: the difference is 4 hours behind in January and 5 hours behind in July. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in Zurich and São Paulo
The two cities side by side. The January column uses the winter offsets (Zurich UTC+01:00, São Paulo UTC−03:00); the July column uses the summer offsets (Zurich UTC+02:00, São Paulo UTC−03:00).

The time difference between Zurich and São Paulo
The difference is not constant. In January São Paulo is 4 hours behind Zurich; in July it is 5 hours behind Zurich. The difference changes on Sunday, 29 March 2026 (from 4 hours behind to 5 hours behind) and Sunday, 25 October 2026 (from 5 hours behind to 4 hours behind) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in Zurich is 05:00 in São Paulo in January and 04:00 in July; 17:00 in Zurich — the end of the working day — is 13:00 in São Paulo in January and 12:00 in July. To go the other way, subtract it: 09:00 in São Paulo is 13:00 in Zurich in January. The time difference calculator does the arithmetic for any date, and the UTC to São Paulo page gives the full conversion table for São Paulo.
Meeting overlap between Zurich and São Paulo
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in Zurich's working day and shows what time they are in São Paulo.
January
| Zurich time | São Paulo time | Both working? |
|---|---|---|
| 09:00 | 05:00 | Yes |
| 10:00 | 06:00 | Yes |
| 11:00 | 07:00 | Yes |
| 12:00 | 08:00 | Yes |

July
| Zurich time | São Paulo time | Both working? |
|---|---|---|
| 09:00 | 04:00 | No |
| 10:00 | 05:00 | No |
| 11:00 | 06:00 | No |
| 12:00 | 07:00 | No |
| 13:00 | 08:00 | No |
| 14:00 | 09:00 | No |
| 15:00 | 10:00 | No |
| 16:00 | 11:00 | No |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Zurich time. In July it is 0 hours: there is no hour when both cities are in their working day. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in Zurich and São Paulo
Zurich observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+01:00 to UTC+02:00.
São Paulo does not observe daylight saving, so its offset of UTC−03:00 never changes.
The difference changes on Sunday, 29 March 2026 and Sunday, 25 October 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — Zurich DST 2026 and São Paulo DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Zurich (05:00–13:00 in São Paulo). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in Zurich it is 05:00 in São Paulo in January; when it is 12:00 in Zurich it is 08:00 in São Paulo; when it is 17:00 in Zurich it is 13:00 in São Paulo. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between the Americas and Europe is the easiest intercontinental case: the difference is 5–9 hours, so the working days overlap for several hours. The best window is late morning in Zurich and afternoon in São Paulo (or the reverse), when both sides are in their working day. Watch the three weeks in March when the United States has changed its clocks and Europe has not — the overlap shifts by an hour, and standing meetings land at the wrong time.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in Zurich and time in São Paulo — explain each city's time zone, and the DST pages — Zurich DST 2026 and São Paulo DST 2026 — give the exact change dates.
