Questions people ask
How do you convert a time between India and another time zone?
Choose the date, the time and the zone you're converting from, such as India (IST), then pick a zone to show. The converted time appears with a table of about 30 cities, including New York, London, Dubai and Singapore. Daylight saving is applied for the date you pick, using the time zone data built into your browser.
- UTC+5:30 India (IST). No daylight saving.
- 30 Cities. Shown together.
- DST Handled. For the date you pick.
- 24h Time. No am/pm mix-ups.
What is the time difference between India and the US?
India, on IST (UTC+05:30), is 10 hours 30 minutes ahead of New York in winter and 9 hours 30 minutes ahead in summer, when New York moves to daylight saving time. Los Angeles is a further three hours behind New York. The tool applies the right offset for the date you pick.
Does it handle daylight saving?
Yes, for the date you choose, using the time zone database built into your browser. India doesn't use daylight saving, so IST stays the same all year, but the gap to the US, UK, Europe and Australia changes twice a year. Always pick the actual meeting date.
Why is the date different in some cities?
Time zones span a whole day. A 9 am call in Mumbai on a Tuesday is still Monday evening in New York and Los Angeles, and already Tuesday afternoon in Sydney. The table shows the date next to each city's time, so you can see clearly when the day changes.
What is the time difference between India and the UK?
India is 5 hours 30 minutes ahead of London in winter, on GMT, and 4 hours 30 minutes ahead in summer, when the UK is on British Summer Time. The UK changes its clocks on the last Sundays of March and October, a few weeks apart from the US changes.
What is the time difference between India and Dubai?
Dubai (UTC+04:00) is 1 hour 30 minutes behind India all year, because neither country uses daylight saving. So 10 am in India is 8:30 am in Dubai. Many Indian businesses serve customers in the Gulf, and this simple gap makes planning calls there easy. The same gap applies to Abu Dhabi and Muscat.
How do I schedule a meeting across time zones?
Pick a candidate time in your own zone and check the table for every participant's city. Look for a slot within working hours for everyone. Between India and the US east coast, early morning US time is evening in India, which often works best for both sides.
Which cities are included?
About 30, covering major cities in the Americas, Europe, Africa, the Middle East, Asia and Australia, including New York, Los Angeles, Toronto, London, Paris, Dubai, Riyadh, Karachi, Dhaka, Kathmandu, Singapore, Tokyo and Sydney. Your device's own zone is also offered as an option. Each row shows the date, time and UTC offset.
Why does Nepal have a 45-minute offset?
Nepal (UTC+05:45) is 15 minutes ahead of India. A few countries use half-hour or 45-minute offsets, including India, Nepal, Sri Lanka and parts of Australia. The tool shows the exact offset next to each city, so these unusual gaps are easy to see. Countries choose their offsets for local reasons.
What does UTC mean?
UTC, Coordinated Universal Time, is the reference that all time zones are measured from. IST is UTC+05:30, meaning five and a half hours ahead. Software, flight schedules and servers often use UTC to avoid confusion, so it's useful to know your offset. The table shows each city's UTC offset.
When do US clocks change?
Most of the US moves its clocks forward on the second Sunday of March and back on the first Sunday of November. During the few weeks between US and UK changes, the usual gaps shift by an hour. Picking the actual date in the tool takes care of this.
Can I convert a time from another country to India?
Yes. Choose the other country's zone in 'Convert from', enter its date and time, and read India in the table or pick India as the zone to show. That's handy when a client sends a meeting invite in their own time, or a webinar lists only US times.
Why does it use a 24-hour clock?
A 24-hour time such as 18:30 can't be confused with 6:30 in the morning, which matters when a call crosses midnight in another country. If you prefer am and pm, anything from 13:00 onwards is the afternoon or evening; subtract 12 to get the usual time.
Is anything I enter stored?
No. The conversion runs in your browser with its built-in time zone data, and nothing is sent to our servers. There's no sign-up and the page saves nothing after you close it, so you can plan meetings without sharing your calendar. Close the tab and nothing remains.
Does it work on a phone?
Yes. The date and time open your phone's own pickers, the zones are dropdowns and the city table scrolls on a small screen. It works in any mobile browser, so you can check a call time with a client abroad while you're travelling or away from your desk.
Is the time zone converter free?
Yes, it's free with no sign-up and no limit on use. It's one of the free converters from Marketiism. Businesses on Marketiism can take online bookings with automatic WhatsApp reminders, which helps when customers are in other cities or countries.
