World Time Zones - Balinese Numerals

Input: Compare New York (EST, UTC−5) and London (GMT, UTC+0) at 2 PM London time

Result: New York: 9:00 AM EST. Time difference: 5 hours. Overlapping work hours (9 AM–5 PM local): 2 PM–5 PM London / 9 AM–12 PM New York.

How many time zones are available?

The tool covers all IANA time zones — over 400 zones representing every country and region worldwide, including zones that observe Daylight Saving Time.

Does the world time tool handle Daylight Saving Time?

Yes. The tool automatically adjusts for Daylight Saving Time based on the current date and each zone's DST rules.

Why does my city show a different time than my local clock?

The most common cause is that your device's time zone setting does not match the IANA time zone for your region. For example, India has one IANA zone (Asia/Kolkata, UTC+5:30) but some devices are set to a generic UTC+5:30 offset without the IANA label. Another cause: if you are in a region with disputed or recently changed time zone rules (like certain Mexican states that abolished DST in 2022), the IANA database may not yet reflect the change on older devices.

What is the best meeting time between New York and London?

With standard 9 AM–5 PM work hours in both cities, the overlap window is 9 AM–12 PM New York time (2 PM–5 PM London time), giving you a 3-hour window. This holds in both summer and winter because the 5-hour offset stays constant — New York shifts from EST (UTC−5) to EDT (UTC−4) and London shifts from GMT (UTC+0) to BST (UTC+1) at nearly the same time each year. The Planner tab on this page shows this overlap automatically once you add both cities, and you can adjust the work-hours window if your team starts earlier or later.

What is the best meeting time between London and Dubai?

Dubai does not observe Daylight Saving Time, so the overlap shifts with the seasons. In summer (when London is on BST, UTC+1), the overlap is 9 AM–2 PM London time (12 PM–5 PM Dubai time) — a 5-hour window. In winter (when London is on GMT, UTC+0), it narrows to 9 AM–1 PM London time (1 PM–5 PM Dubai time) — a 4-hour window. The Planner tab accounts for this automatically by computing each city's actual UTC offset for the date you select, so you always see the correct overlap regardless of season.

What is the best meeting time between New York and Tokyo?

There is no overlap between standard 9 AM–5 PM work hours in New York and Tokyo. Tokyo is 13–14 hours ahead of New York (depending on DST), so when it is 9 AM in New York it is already 10–11 PM in Tokyo. For teams split across this gap, the most workable approaches are: rotate the meeting time so the inconvenience alternates rather than always falling on one side; use asynchronous updates (recorded video briefs or shared documents) instead of live meetings; or schedule two shorter check-ins at the edges — one at 8 AM New York / 11 PM Tokyo for the Tokyo side to join from home, and one at 7 PM New York / 8–9 AM Tokyo for the New York side to take in the evening. The Planner tab shows partial overlap suggestions when no full overlap exists, so you can see which hours come closest.

What should I do when there is no overlapping work hours between time zones?

Not every city pair has a workable live-meeting window — New York and Tokyo, or Los Angeles and Mumbai, have zero overlap during standard 9–5 hours. The honest approach is to accept this and design around it rather than forcing someone to take a 2 AM call every week. Three strategies work in practice: (1) rotate the meeting time so the burden alternates between teams rather than always falling on the same side; (2) replace the live meeting with asynchronous updates — a recorded video summary, a shared document, or a written standup that each team reviews during their own work hours; (3) if a live meeting is truly necessary, schedule it at the least-bad time and keep it short (15–20 minutes). The Planner tab shows partial overlap suggestions ranked by how many cities are in work hours, so you can find the least disruptive option.

How does daylight saving time affect meeting planning across time zones?

Daylight Saving Time shifts a city's UTC offset by one hour on transition dates, and different countries transition on different dates — the US shifts in mid-March and early November, while Europe shifts in late March and late October. This means the gap between two cities can change by 1–2 hours twice a year. For example, London and Dubai have a 3-hour difference in summer but a 4-hour difference in winter because Dubai does not observe DST. Tools that use fixed UTC offsets (like "UTC+4" hardcoded) will be wrong for half the year. This tool computes each city's actual offset for the specific date you select using the IANA timezone database, so the Planner tab always reflects the correct overlap — even on the day of a DST transition.

How do I share a meeting time with people in different time zones without confusion?

The Planner tab has a Copy Summary button that copies a plain-text breakdown of the best meeting times to your clipboard, showing each city's local time side by side. You can paste it directly into an email, Slack, or WhatsApp message. For example, it produces something like: "Best meeting times (all cities in work hours): London 9 AM / Dubai 12 PM, London 10 AM / Dubai 1 PM, London 11 AM / Dubai 2 PM." This eliminates the back-and-forth of "what time is that for you?" because every participant sees their own local time in the same message.

How do I compare time zones side by side?

Add two or more cities using the Add button and switch to the Timeline or Grid view. The Timeline view shows a 24-hour bar for each city with the current time highlighted, so you can see at a glance what hour it is in each place. The Grid view shows a compact table of all selected cities with their current local times and analog clocks. The Difference view shows the hour offset between each pair of cities. You can add up to six cities simultaneously.

Can I check what time it will be in another city on a future date?

Yes. Use the date picker or the timeline scrubber to move to any past or future date. The tool recalculates every city's local time for that date, including any DST transitions that occur between now and then. This is useful for scheduling meetings days or weeks ahead, since the UTC offset for some cities changes on DST transition dates.

What is the difference between the Timeline, Grid, Difference, and Planner views?

Timeline shows a 24-hour horizontal bar for each city with work-hours shading, so you can visually scan for overlap. Grid shows a compact table with each city's current time and an analog clock. Difference shows the hour offset between every pair of selected cities. Planner computes the best meeting times by finding hours where all selected cities are within your configurable work-hours window, and ranks them by how many cities are in work hours.

How accurate are the time zone offsets?

All offsets are computed from the IANA timezone database (also called the tz database), which is the same source used by operating systems, programming languages, and major scheduling platforms. The database is updated several times per year as governments change DST rules or time zone boundaries. This tool uses the browser's Intl API, which relies on the device's bundled IANA data, so the accuracy depends on your device being reasonably up to date. For critical scheduling, always confirm the time with participants directly.

Can I use this world clock for free without signing up?

Yes. The tool is entirely free, requires no account, no sign-up, and no app install. It runs in your browser and your selected cities are saved locally on your device. Nothing is sent to any server.

How do I convert Eastern Time to Pacific Time?

Add cities in the Eastern and Pacific time zones and choose the date you need. The tool applies the correct offset automatically: Eastern Time is normally three hours ahead of Pacific Time. During the brief weeks when the United States and another region change daylight saving time on different dates, the difference can temporarily be two or four hours, so a date-aware converter is safer than memorizing a fixed offset.

How do I convert Central Time to Eastern Time?

Select a city in Central Time and a city in Eastern Time. Eastern Time is normally one hour ahead of Central Time. The converter uses the selected date to account for daylight saving changes and displays both local times side by side.

How do I convert Pacific Time to Eastern Time?

Select cities in both zones and choose the date. Pacific Time is normally three hours behind Eastern Time. The tool calculates the actual local time for that date instead of relying on a fixed abbreviation, which helps around daylight saving transitions.

How do I convert UTC to Eastern Standard Time?

Add a city that uses Eastern Time and compare it with UTC. Eastern Standard Time is UTC−5, while Eastern Daylight Time is UTC−4. Choose the date because the correct offset depends on whether daylight saving time is active.

How do I convert IST to EST?

Add a city in India and a city in the US Eastern zone, then choose the date. India Standard Time is UTC+5:30 and does not observe daylight saving time. US Eastern Time changes between UTC−5 and UTC−4, so the difference is usually 10.5 or 9.5 hours depending on the season.

How do I convert GMT to EST?

Compare a GMT city such as London during standard time with a city in the US Eastern zone. GMT is UTC+0 and EST is UTC−5, so EST is five hours behind GMT. London may use BST in summer, and the US may use EDT, so choose a date for an accurate result.

What time zone is India in?

India uses one national time zone: India Standard Time (IST), equal to UTC+5:30. India does not observe daylight saving time, so the offset remains the same throughout the year. Add a city such as New Delhi or Mumbai to compare IST with any other selected city.

What time zone is Japan in?

Japan uses Japan Standard Time (JST), equal to UTC+9. Japan does not observe daylight saving time. Add Tokyo or another Japanese city to compare its local time with the other cities in your timeline or grid.

How many time zones does the United States have?

The United States spans several time zones, including Eastern, Central, Mountain, Pacific, Alaska, and Hawaii-Aleutian, plus additional zones in territories. Not every state observes daylight saving time in the same way. Search for the specific city rather than assuming the whole state uses one offset.

How do I find the time zone for a city?

Search for the city in the Add City field. The tool identifies the city's IANA time zone and shows its current UTC offset for the selected date. City-based lookup is more reliable than choosing an abbreviation such as CST, which can refer to different regions.

How do I find the time zone I am currently in?

The tool can use your browser's local time-zone setting to identify your current IANA zone. Check your device settings if the result looks wrong, especially when using a VPN or traveling. You can also search for your current city and compare the two results.

How do I plan a meeting across multiple time zones?

Add every participant's city, set the work-hours start and end, and open Planner. The tool checks the full day and ranks times by how many cities are inside working hours. If no perfect overlap exists, choose a partial overlap and rotate the inconvenient time between teams.

What is the best international meeting time?

There is no universal best time because it depends on the cities and working hours. Add all locations to Planner and use the overlap suggestions rather than guessing from one pair. For global teams, a rotating schedule or asynchronous updates may be fairer than placing the earliest or latest meeting on the same group every week.

How do I schedule a meeting across different time zones without DST mistakes?

Choose the actual meeting date before copying a proposed time. The tool computes each city's offset for that date, including daylight saving rules. Share the city-by-city summary instead of only saying "3 PM Eastern," because the offset can change later in the year.

How do I compare time zones side by side on a world clock?

Add the cities you want to compare and use Grid for a compact table or Timeline for a visual 24-hour comparison. Difference view shows the offset between pairs, while Planner highlights the hours that fall inside your chosen work window.

Can I convert time zones for a future date?

Yes. Use the date picker or timeline scrubber to choose a future date. The tool recalculates each city's local time and UTC offset for that date, including daylight saving transitions.

Why does the time difference change during the year?

Some locations change their clocks for daylight saving time while others do not, and countries may change on different dates. A pair that is five hours apart can temporarily become four or six hours apart. The tool uses the selected date and IANA rules to show the correct difference.

What is the difference between a time zone and a UTC offset?

A UTC offset is a numeric difference from UTC, such as UTC+5:30. A time zone is a named region with historical and future rules, such as Asia/Kolkata or America/New_York. Two cities can share an offset today but have different daylight saving or historical rules, so the named zone is better for scheduling.

How do I convert Australia time to another country?

Search for the specific Australian city because Australia spans several zones and daylight saving rules differ by state. Add the destination city and select the date. The tool computes both local times and avoids treating all of Australia as one offset.

How do I convert London time to Dubai time?

Add London and Dubai, then choose the date. Dubai stays on UTC+4 year-round, while London changes between GMT and BST. The difference is normally four hours in winter and three hours in UK summer.

How do I convert New York time to Tokyo time?

Add New York and Tokyo and choose the meeting date. Tokyo stays on JST (UTC+9), while New York changes between EST and EDT, so the difference is normally 13 or 14 hours. Planner can show the least-disruptive overlap when normal work hours do not overlap.

Can I use the world time zone planner for remote teams?

Yes. Add each team member's city, define the team's working hours, and use Planner to rank overlapping times. Copy the city-by-city summary to email, chat, or a calendar invite so everyone sees the local time without manual conversion.

How do I avoid confusing CST, EST, PST, and IST abbreviations?

Use city names or IANA zones whenever possible. Abbreviations are ambiguous: CST can mean US Central Standard Time, China Standard Time, or Cuba Standard Time, and IST can mean India, Irish, or Israel Standard Time. The city search removes that ambiguity.

Does the time zone converter handle half-hour and quarter-hour offsets?

Yes. The tool uses actual regional offsets, including India at UTC+5:30, Nepal at UTC+5:45, and some Australian zones at half-hour offsets. These are displayed correctly in the grid, timeline, and difference views.

How accurate is the world time zone converter?

The browser uses IANA time-zone data through the Intl API, the same general rules used by operating systems and scheduling software. Keep your device updated because governments can change time-zone rules. For a critical event, confirm the final local time with participants.

Can I use the time zone calculator offline?

After the page loads, the calculations run in your browser and do not require a live connection. Your selected cities are stored locally. New city searches or updates may require the page to be loaded again if the browser has not cached the needed data.

How do I convert time between India and the United States?

Add an Indian city and the specific US city, then choose the date. India stays at UTC+5:30, while US cities change between standard and daylight time. The exact difference therefore depends on whether you compare India with Eastern, Central, Mountain, or Pacific Time and on the date selected.

How do I find overlapping work hours for three or more countries?

Add every city to the Planner and set the working-hours window for the group. The tool checks each hour and ranks the times by the number of cities inside their work windows. When a full overlap does not exist, use the highest-ranked partial overlap and rotate the inconvenient time fairly.

Where is the Balinese script still used today?

The Balinese script (Aksara Bali) is actively used in Hindu temple ceremonies, traditional calendar systems, and cultural inscriptions on palm leaves (lontar). It is taught in Balinese schools as part of local content curriculum. While daily communication uses Latin script, the Balinese script remains alive in religious and cultural contexts, making it one of the more actively used traditional Indonesian scripts.
