About Time Zone Converter
Free time zone converter. Convert times between any two time zones instantly. Compare cities side by side, find meeting times across regions, and handle daylight saving.
How to use
- Select the source time zone from the dropdown or search by city name. The converter includes all major world time zones with their UTC offsets, covering over 400 cities and regions. Common selections: EST (Toronto, New York), PST (Vancouver, Los Angeles), GMT (London), CET (Paris, Berlin), JST (Tokyo).
- Enter the time you want to convert using the time picker or by typing directly. You can enter a specific time or use the current time button to automatically fill in the present time in the selected source zone.
- Select one or more destination time zones. The converter shows the equivalent time in each destination zone simultaneously. Compare meeting times across multiple time zones at a glance — essential for coordinating across international teams.
- Toggle daylight saving time (DST) awareness. During DST transitions, the same UTC offset can correspond to different local times. The converter automatically accounts for DST based on the selected cities and the date, so a Toronto-to-London conversion is always accurate regardless of whether one or both locations are observing DST.
- Use the meeting planner mode to find overlapping business hours across multiple time zones. Enter the working hours for each location and the converter highlights the windows where all participants are within their normal business hours.
- Save frequently used time zone pairs for quick access. If you regularly coordinate between Toronto and London or Vancouver and Sydney, saved pairs let you convert with a single click.
Frequently asked questions
What time is it in different cities right now?
Time zones span 24 hours around the globe. When it is 12:00 PM (noon) in Toronto (EST/UTC-5): it is 9:00 AM in Vancouver (PST/UTC-8), 5:00 PM in London (GMT/UTC+0), 6:00 PM in Paris (CET/UTC+1), 10:30 PM in Mumbai (IST/UTC+5:30), 1:00 AM the next day in Beijing (CST/UTC+8), 2:00 AM the next day in Tokyo (JST/UTC+9), and 6:00 AM the next day in Sydney (AEDT/UTC+11). These offsets shift when daylight saving time starts or ends in different countries at different dates. This converter always shows current accurate times.
When does daylight saving time change?
In Canada and the US, DST begins on the second Sunday of March (clocks spring forward 1 hour) and ends on the first Sunday of November (clocks fall back 1 hour). Saskatchewan and parts of BC do not observe DST. In Europe, DST begins the last Sunday of March and ends the last Sunday of October. Most of Asia, Africa, and South America do not observe DST. The 2-3 week gap between North American and European DST transitions means the time difference between Toronto and London is 4 hours for a few weeks instead of the usual 5 hours. This converter accounts for all DST transitions automatically.
How do I schedule a meeting across time zones?
Find the overlapping business hours between locations. Toronto (EST) business hours 9 AM - 5 PM overlap with London (GMT) 2 PM - 10 PM, giving a practical window of 9 AM - 12 PM EST (2 PM - 5 PM London). For Toronto and Tokyo (JST, +14 hours): Toronto 8 AM is Tokyo 10 PM, and Toronto 5 PM is Tokyo 7 AM the next day — meaning a 7-8 AM JST or 5-6 PM EST slot works best. This converter's meeting planner mode visualizes these overlaps automatically, showing green blocks where all participants are within their working hours. Use the
Date Calculator to find how many business days fall within a project deadline across time zones when scheduling international deliverables.
What is UTC and how does it differ from GMT?
UTC (Coordinated Universal Time) is the primary time standard used worldwide. GMT (Greenwich Mean Time) is a time zone centred on the prime meridian at the Royal Observatory in Greenwich, London. For practical purposes, UTC and GMT represent the same time, but UTC is the technical standard used in computing, aviation, and military applications, while GMT is the casual term used for the UK time zone. UTC does not observe daylight saving time. During summer, the UK switches to BST (British Summer Time, UTC+1), while UTC remains constant. All world time zones are defined as offsets from UTC.
How many time zones does Canada have?
Canada spans six time zones from east to west: Newfoundland (NST, UTC-3:30 — the only half-hour offset in North America), Atlantic (AST, UTC-4), Eastern (EST, UTC-5), Central (CST, UTC-6), Mountain (MST, UTC-7), and Pacific (PST, UTC-8). When it is noon in Toronto, it is 1:30 PM in St. John's, 1:00 PM in Halifax, 11:00 AM in Winnipeg, 10:00 AM in Calgary, and 9:00 AM in Vancouver. Most provinces observe daylight saving time except Saskatchewan (stays on CST year-round) and parts of northeastern BC.
What is the International Date Line?
The International Date Line (IDL) is an imaginary line roughly following the 180th meridian in the Pacific Ocean where the calendar date changes. Crossing the IDL westward advances the date by one day. Crossing eastward moves the date back by one day. This is why flying from Vancouver to Sydney crossing the date line means you arrive 2 calendar days later despite only 15 hours of flight time. The IDL is not perfectly straight — it zigzags to avoid splitting countries across different dates. Some Pacific island nations have shifted sides of the line for economic convenience.
Why do some time zones have 30 or 45-minute offsets?
While most time zones use whole-hour UTC offsets, several regions use fractional offsets: India (UTC+5:30), Iran (UTC+3:30), Afghanistan (UTC+4:30), Nepal (UTC+5:45), Myanmar (UTC+6:30), the Chatham Islands of New Zealand (UTC+12:45), and Newfoundland, Canada (UTC-3:30). These offsets were adopted to better align the local solar noon with 12:00 on the clock, as a full 1-hour shift would have been too much for the geographic location. India's single UTC+5:30 zone covers the entire country despite spanning 2,000+ km east to west, meaning sunrise times vary by up to 90 minutes between eastern and western India.
