About Time Zone Converter
The OmniTools360 Time Zone Converter shows what a given date and time in one place is in other cities around the world. It starts with your browser's time zone, lists popular zones such as UTC, New York, London, Dubai, India, Singapore, Tokyo, and Sydney, and accounts for daylight saving time automatically. It is free and runs in your browser.
How does the Time Zone Converter work?
The tool turns the date and time you enter into one exact moment using the rules of the source time zone, including any daylight saving change on that date. It then formats that same moment in each target zone with your browser's built-in time zone database, and shows each zone's UTC offset and whether it falls on the next or previous day.

Frequently Asked Questions about Time Zone Converter
How do I convert time between two time zones?
Enter the date and time, choose the source time zone, and the converter shows the matching time in every city you have added. It works out the exact moment in UTC and then applies each target zone's offset for that date, so the result already accounts for daylight saving time where it applies.
Does the time zone converter handle daylight saving time?
Yes. Offsets are looked up for the exact date you choose using your browser's time zone database. For example, London is UTC+0 in winter and UTC+1 in summer. Because the US and Europe change clocks on different dates, the gap between New York and London is briefly four hours instead of five each spring and autumn.
What does UTC+5:30 mean?
UTC+5:30 means the local time is five hours and thirty minutes ahead of Coordinated Universal Time. India uses this offset all year. Some zones use 30 or 45 minute offsets, such as Nepal at UTC+5:45, and the converter shows these exact offsets on each card so you can compare zones easily.
Why does a converted time show Next day or Previous day?
The label appears when the converted time falls on a different calendar date than the date you entered. For example, 9:00 AM on 10 March in New York is already midnight on 11 March in Sydney. This helps avoid booking a meeting on the wrong day for colleagues far east or west of you.
How do I schedule a meeting across time zones?
Add every attendee's city, then change the time until it lands within working hours for everyone, usually between 9:00 and 18:00 local time. Click Copy All to paste the list of local times into your invite. Everything runs in your browser, and nothing you enter is uploaded or stored.
