The world is divided into 24 primary time zones, each roughly 15 degrees of longitude wide, corresponding to one hour of time difference. However, political and geographic boundaries mean many real-world zones deviate significantly from this pattern.
When scheduling across time zones, always confirm whether DST applies to both locations. Spring and autumn transitions often fall on different dates in different countries, causing temporary shifts in the offset between two zones.
A meeting is scheduled for 2:00 PM EST (Toronto). What time is it in other cities? Vancouver (PST): 11:00 AM (3 hours behind). London (GMT): 7:00 PM (5 hours ahead). Paris (CET): 8:00 PM (6 hours ahead). Mumbai (IST): 12:30 AM next day (10.5 hours ahead). Tokyo (JST): 4:00 AM next day (14 hours ahead). Sydney (AEDT): 6:00 AM next day (16 hours ahead during Australian summer).
The US and Canada switch DST on the second Sunday in March and first Sunday in November. Europe switches about 2–3 weeks later in spring and earlier in fall. During the gap between these switch dates, the offset between North America and Europe is temporarily 1 hour different from normal — a common source of confusion for international teams. Always use a time zone converter for the specific date of your meeting, not a static offset chart.
Notable DST non-participants: Saskatchewan (Canada) stays on CST year-round. Arizona (USA, except the Navajo Nation) stays on MST year-round. Japan, China, India have no DST. Most of Africa does not observe DST. This means that a business relationship between, say, Toronto and Saskatoon involves a time difference that shifts seasonally — they are 1 hour apart in winter and the same time in summer.
This free time zone converter lets you instantly convert any time between any two world time zones. Whether you are scheduling an international meeting, coordinating with a remote team, or planning travel across continents, this world clock tool shows the exact local time in hundreds of cities and countries simultaneously. Simply select your source time zone and target time zones, then enter the time you want to convert.
The converter supports all major time zones including UTC, EST, PST, GMT, CET, IST, JST, AEST, and many more. It automatically accounts for Daylight Saving Time (DST) where applicable, so the converted times are always accurate for the current date. This is the fastest free time zone converter available — no app, no sign-up, just instant answers.
For practical purposes they are the same. GMT (Greenwich Mean Time) is a time zone based on the Earth's rotation at 0° longitude. UTC (Coordinated Universal Time) is a more precise standard maintained by atomic clocks. In everyday use — scheduling meetings, setting timestamps, expressing offsets — UTC and GMT are interchangeable.
Canada spans 6 standard time zones: Newfoundland (UTC−3:30), Atlantic (UTC−4), Eastern (UTC−5), Central (UTC−6), Mountain (UTC−7), and Pacific (UTC−8). During Daylight Saving Time most of these shift forward 1 hour. Saskatchewan observes Mountain Standard Time year-round without DST.
Most of Canada observes DST — clocks spring forward on the second Sunday in March and fall back on the first Sunday in November. Major exceptions: Saskatchewan (stays on CST year-round), parts of northeastern BC, and a few communities in Ontario and Quebec near the Manitoba border.
Toronto is in the Eastern Time Zone. In winter (standard time) it is EST — UTC−5. In summer (daylight time, March–November) it is EDT — UTC−4. The same zone applies to Ottawa, Montreal, and most of Ontario and Quebec.
Pacific Time (PST/PDT) is always 3 hours behind Eastern Time (EST/EDT). To convert: subtract 3 hours. For example, 2:00 PM EST = 11:00 AM PST. During DST, both zones shift together, so the 3-hour gap remains constant year-round between these two zones.
Newfoundland Standard Time (NST, UTC−3:30) dates to the 19th century when local solar time for St. John's was established. When global time zones were standardized, Newfoundland retained this historically established half-hour offset. It is one of only a handful of half-hour time zones in the world, alongside India (UTC+5:30), Iran (UTC+3:30), and a few others.
Use this converter to find a time within business hours (9 AM–5 PM) for all participants. Good overlap windows: North America ↔ Europe: 9 AM–12 PM EST (2–5 PM GMT). North America ↔ India: 7:30–9:30 AM EST (6–8 PM IST). North America ↔ Asia-Pacific: very difficult — typically requires one side taking an early morning or late evening slot.
A Unix timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC — called the Unix Epoch. It is widely used in programming, databases, and APIs to store date/time as a single integer. For example, April 16, 2026, 12:00:00 UTC ≈ Unix timestamp 1,776,081,600. Converting between Unix timestamps and human-readable dates is straightforward with a time zone converter.
