When it is 09:00 in Bangkok it is 21:00 in Toronto in January and 22:00 in July. Toronto is 12 hours behind Bangkok right now — but it is not constant: the difference is 12 hours behind in January and 11 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 Bangkok and Toronto
The two cities side by side. The January column uses the winter offsets (Bangkok UTC+07:00, Toronto UTC−05:00); the July column uses the summer offsets (Bangkok UTC+07:00, Toronto UTC−04:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Bangkok and time in Toronto — explain each city's time zone, offsets and daylight saving in full.
The time difference between Bangkok and Toronto
The difference is not constant. In January Toronto is 12 hours behind Bangkok; in July it is 11 hours behind Bangkok. The difference changes on Sunday, 8 March 2026 (from 12 hours behind to 11 hours behind) and Sunday, 1 November 2026 (from 11 hours behind to 12 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 Bangkok is 21:00 in Toronto in January and 22:00 in July; 17:00 in Bangkok — the end of the working day — is 05:00 in Toronto in January and 06:00 in July. To go the other way, subtract it: 09:00 in Toronto is 21:00 in Bangkok in January. The time difference calculator does the arithmetic for any date, and the UTC to Toronto page gives the full conversion table for Toronto.
Meeting overlap between Bangkok and Toronto
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 Bangkok's working day and shows what time they are in Toronto.
January
| Bangkok time | Toronto time | Both working? |
|---|---|---|
| 09:00 | 21:00 | Yes |
| 10:00 | 22:00 | Yes |
| 11:00 | 23:00 | Yes |
| 12:00 | 00:00 | Yes |
| 13:00 | 01:00 | Yes |
| 14:00 | 02:00 | Yes |
| 15:00 | 03:00 | Yes |
| 16:00 | 04:00 | Yes |
July
| Bangkok time | Toronto time | Both working? |
|---|---|---|
| 09:00 | 22:00 | No |
| 10:00 | 23:00 | No |
| 11:00 | 00:00 | No |
| 12:00 | 01:00 | No |
| 13:00 | 02:00 | No |
| 14:00 | 03:00 | No |
| 15:00 | 04:00 | No |
| 16:00 | 05:00 | No |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Bangkok 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 Bangkok and Toronto
Bangkok does not observe daylight saving, so its offset of UTC+07:00 never changes.
Toronto observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−05:00 to UTC−04:00.
The difference changes on Sunday, 8 March 2026 and Sunday, 1 November 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 — Bangkok DST 2026 and Toronto DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Bangkok (21:00–05:00 in Toronto). 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 Bangkok it is 21:00 in Toronto in January; when it is 12:00 in Bangkok it is 00:00 in Toronto; when it is 17:00 in Bangkok it is 05:00 in Toronto. The difference is 12 hours or more, so the two cities are on different dates for part of the day: when it is Monday morning in Bangkok, it is still Sunday in Toronto if Toronto is behind, or already Monday evening if it is ahead. Always state the date as well as the time when you schedule across this pair. Scheduling between the Americas and Asia is the hardest case in time-zone work: the difference is 12 hours or more, so one side's working day is the other's night. The only workable approach is to meet at the edge of the day — early morning in Bangkok and evening in Toronto, or the reverse — and to keep the meeting short. Rotate the awkward hour week by week, or the same side will always be the one giving up its evening. Record the meeting and share notes, so the side that could not attend can still follow the decision.

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 Bangkok and time in Toronto — explain each city's time zone, and the DST pages — Bangkok DST 2026 and Toronto DST 2026 — give the exact change dates.
