Current Time by City & Supported Time Zones
This world clock utilizes standard International Components for Unicode (ICU) and the Internet Assigned Numbers Authority (IANA) time zone database. Below are the default metropolitan regions monitored:
| City | Country | IANA Identifier |
|---|---|---|
| New Delhi | India | Asia/Kolkata |
| London | United Kingdom | Europe/London |
| New York | United States | America/New_York |
| San Francisco | United States | America/Los_Angeles |
| Tokyo | Japan | Asia/Tokyo |
| Singapore | Singapore | Asia/Singapore |
| Sydney | Australia | Australia/Sydney |
| Dubai | United Arab Emirates | Asia/Dubai |
Calculations handle daylight saving transitions automatically according to each jurisdiction's legal seasonal rules without manual offset adjustments.
The clock functions entirely by parsing standard time zone identifiers without prompting for or storing your precise GPS coordinates.
Frequently Asked Questions
How does the clock determine day and night status?
The tool evaluates the current civil hour in each specific time zone, rendering a daytime sun indicator between 06:00 and 18:00 and an evening moon indicator during nighttime hours.
Can I customize which cities are shown?
Yes. Use the dropdown selector to add cities or click the trash icon to remove any card. Your chosen list persists locally in your browser.
