Current Time Around the World
What is Timezone Converter?
A timezone converter translates dates and times between any two of the world's time zones, accounting for daylight saving time (DST) transitions automatically. With remote work spanning multiple continents, international business, and global collaboration, timezone conversion is a daily need. This tool shows you what time it is right now in major cities worldwide and lets you convert any specific date/time from one zone to another — essential for scheduling meetings, coordinating deployments, planning international events, and understanding when deadlines fall in your local time.
How It Works
Select a source timezone and target timezone, then enter a date and time. The tool uses the browser's Intl.DateTimeFormat API with the IANA timezone database — the same authoritative source used by operating systems and servers worldwide. It automatically handles DST transitions, historical timezone changes, and fractional-hour offsets (like India's +5:30 or Nepal's +5:45). The current time in popular timezones updates live every second, and converted times show the timezone abbreviation and UTC offset for clarity.
Common Use Cases
- •Scheduling meetings across timezones for globally distributed teams
- •Planning deployment windows that fall outside business hours in all affected regions
- •Converting event start times for international conferences and webinars
- •Understanding when production alerts fired relative to your local time for on-call debugging
- •Coordinating launch times for simultaneous global product releases or marketing campaigns
- •Converting trading market open/close times between financial centers (NYSE, LSE, TSE)
Frequently Asked Questions
How do I convert time between timezones?▼
Select your source timezone and target timezone, enter the date and time, and the tool instantly shows the converted time.
Does it handle daylight saving time?▼
Yes, the tool uses your browser's built-in timezone database which automatically accounts for DST transitions.
What timezones are supported?▼
All major timezones are supported including UTC, US time zones, European, Asian, Australian, and more.
Why should I schedule meetings in UTC?▼
Because UTC has no daylight saving, so it never shifts. A meeting fixed at 14:00 UTC is unambiguous year-round, whereas one fixed at "9am New York time" moves relative to London for two weeks each spring and autumn, when the two regions change clocks on different dates.
What is the difference between UTC, GMT and Zulu time?▼
In everyday use they refer to the same clock time. UTC is the modern atomic standard, GMT is a timezone that Britain uses in winter (moving to BST in summer), and Zulu is the aviation and military name for UTC, written with a trailing Z as in `14:00Z`.
Do all timezones differ from UTC by whole hours?▼
No. India is UTC+05:30, Nepal is UTC+05:45, and parts of Australia use UTC+08:45 or UTC+09:30. Assuming whole-hour offsets is a common bug in scheduling code, as is assuming the offset for a location never changes.
