World Clock — Free Online

How the World Clock Works

You pick the cities or timezones you want to track — Mumbai, New York, London, Tokyo, Dubai, anywhere — and the tool displays the current time in each, updated every second from your device's clock using the IANA timezone database that ships with modern browsers. Daylight saving transitions are handled automatically because the browser knows the rules for each zone.

There's no server fetch for time — the calculation runs in JavaScript using the system clock and timezone offsets. Your selected cities persist in browser local storage so the list is there next time you visit. No signup, no account, no sync to a server. The clock face renders with date in DD-MM-YYYY and time in 12-hour or 24-hour format.

When to Use the World Clock

Remote teams scheduling meetings across continents without mental math. Freelancers tracking client business hours in different countries. Travellers checking what time it is back home. Trading and finance professionals watching market open and close times in NYSE, LSE, NSE, and TSE. Family members keeping in mind a good time to call relatives abroad.

Why Use Toolkiya's World Clock

Most online world clocks are stuffed with banner ads, popups asking for notification permission, and tracking scripts that follow you afterward. Toolkiya's runs entirely in your browser using built-in timezone data. No signup, no account, no analytics tracking which cities you watch. The list of cities you add is stored in local storage on your device, not on a server. The page loads fast because there's no ad loader or external tracker.

Tips for the World Clock

Daylight saving changes shift offsets by an hour twice a year in most western countries — India does not observe DST. When scheduling, double-check on the actual transition dates (March and November in the US, late March and October in Europe). Use 24-hour format for international scheduling to avoid AM/PM confusion.
