What is a World Clock?
A world clock is a tool that simultaneously displays the current local time in multiple cities or time zones around the globe. Unlike a single clock showing your local time, a world clock lets you see at a glance what time it is right now in Mumbai, Dubai, London, New York, Tokyo, and any other location you care about. This is invaluable for anyone who works across borders, communicates with friends and family abroad, or travels internationally.
World clocks are essential for businesses with international clients, remote teams spread across continents, and individuals managing relationships or transactions across different time zones. Rather than mentally calculating "if it's 3 PM here, what time is it there?", a world clock does the heavy lifting instantly and accurately.
How to Use the World Clock
Using this world clock is straightforward. Follow these steps to get started:
- Add cities: Use the dropdown in Section 1 to select a city or timezone. Click "Add Clock" to add it to your live display. You can add as many cities as you need — they are saved automatically in your browser.
- Read live times: The clock grid (Section 2) shows the current time, date, timezone abbreviation, UTC offset, and the time difference from IST for each city. The coloured left border indicates the time of day — amber for morning, blue for daytime, violet for evening, and slate for night.
- Convert meeting times: Use the Meeting Time Planner (Section 3) to find what a specific time in one city corresponds to in all other cities you've added. Simply set the time, date, and source timezone, then click "Convert".
- Remove clocks: Click the × button on any card to remove it. Use "Clear All" to start fresh.
Time Zones Explained
The world is divided into 24 primary time zones, each offset from Coordinated Universal Time (UTC) by a whole or half hour. Some regions use offsets of 15, 30, or 45 minutes — India (UTC+5:30) and Nepal (UTC+5:45) are well-known examples. Many countries observe Daylight Saving Time (DST), advancing their clocks by one hour in summer to make better use of daylight.
| Region | UTC Offset (Standard) | DST? |
|---|---|---|
| India (IST) | UTC+5:30 | No |
| UAE (GST) | UTC+4:00 | No |
| UK (GMT/BST) | UTC+0 / UTC+1 | Yes (+1 in summer) |
| France/Germany (CET/CEST) | UTC+1 / UTC+2 | Yes (+1 in summer) |
| Russia (MSK) | UTC+3:00 | No (abolished 2014) |
| USA East (EST/EDT) | UTC-5 / UTC-4 | Yes (+1 in summer) |
| USA West (PST/PDT) | UTC-8 / UTC-7 | Yes (+1 in summer) |
| Singapore (SGT) | UTC+8:00 | No |
| Japan (JST) | UTC+9:00 | No |
| Australia/Sydney (AEST/AEDT) | UTC+10 / UTC+11 | Yes (+1 in summer) |
Popular Time Differences from India (IST)
India does not observe Daylight Saving Time, so the IST offset remains constant at UTC+5:30 year-round. The table below shows the time difference from IST to major cities. Differences may shift by 1 hour when those cities observe DST.
| City | Timezone | UTC Offset | Difference from IST |
|---|---|---|---|
| Dubai | GST | UTC+4 | −1.5 hrs |
| Karachi | PKT | UTC+5 | −0.5 hrs |
| Dhaka | BST | UTC+6 | +0.5 hrs |
| Bangkok | ICT | UTC+7 | +1.5 hrs |
| Singapore | SGT | UTC+8 | +2.5 hrs |
| Beijing / Shanghai | CST | UTC+8 | +2.5 hrs |
| Tokyo | JST | UTC+9 | +3.5 hrs |
| Sydney | AEST | UTC+10 | +4.5 hrs (standard) |
| London | GMT | UTC+0 | −5.5 hrs (winter) |
| Paris / Berlin | CET | UTC+1 | −4.5 hrs (winter) |
| Moscow | MSK | UTC+3 | −2.5 hrs |
| New York | EST | UTC−5 | −10.5 hrs (winter) |
| Chicago | CST | UTC−6 | −11.5 hrs (winter) |
| Los Angeles | PST | UTC−8 | −13.5 hrs (winter) |
| São Paulo | BRT | UTC−3 | −8.5 hrs |
Tips for Scheduling International Meetings
Scheduling across time zones is one of the most common pain points in international business and remote work. Here are practical strategies to make it easier:
- Find the overlap window: Identify the hours when all participants are within their standard working hours (typically 9 AM – 6 PM). Use the Meeting Time Planner above to find a slot that works for everyone.
- Account for DST transitions: Countries that observe Daylight Saving Time shift their clocks in spring and autumn. This can change the overlap window by an hour. India, UAE, Singapore, Japan, and Russia do not observe DST.
- Always confirm in UTC: When sharing a meeting time across multiple parties, include the UTC equivalent (e.g. "Meeting at 10:00 AM IST / 04:30 UTC") to eliminate ambiguity.
- Rotate the inconvenient slot: If a meeting consistently falls outside normal hours for one party, rotate the schedule so the inconvenience is shared fairly over time.
- India–USA overlap: For IST and US East Coast (EST), a common overlap window is 7:30 PM – 9:30 PM IST, which is 9:00 AM – 11:00 AM EST. For PST, the window shifts 3 hours later.
- India–UK overlap: With London on BST (summer), the overlap is roughly 12:00 PM – 5:00 PM IST, which covers standard UK morning hours. In winter (GMT), subtract 1 hour from the London side.
