World Time Buddy — compare world clocks & convert timezones instantly
easyTime is a free world time buddy and timezone calculator that shows the current time in every city you care about side by side. Add up to 24 timezones, switch between a comparison table, grid cards, analog world clocks, or digital clocks, and use the time machine slider to see any moment up to 3 days in the past or 7 days in the future. Tap any hour to run an instant timezone conversion — for example, what 4 PM in London equals in IST, New York, or Tokyo.
Timezone converter & meeting planner
The hour-by-hour table marks columns where all your selected zones fall within 8 AM – 8 PM, making it a quick meeting-time finder for distributed teams. Late-night hours are shaded, day offsets (±1 day) and weekend flags are shown per zone, and daylight saving time is handled automatically for the exact date you view.
World clock in 4 styles
Choose the table view for precision, grid cards for a glanceable dashboard, smooth analog clock faces, or live-ticking digital clocks. Your selection is remembered and can be shared with a single link that encodes your timezones, view, and home zone.
Private, offline & installable
Everything runs on your device using the browser’s built-in IANA timezone database — no API calls, no accounts, no tracking. Install easyTime as a progressive web app for one-tap access even when you are offline.
Frequently asked questions
What is a world time buddy?
A world time buddy is a tool that lets you compare the current time across multiple cities and timezones at once, and see what any future hour in one timezone equals in another — for example, what 4 PM in London is in IST.
How do I convert 4 PM London time to IST?
Add London and your home timezone, switch to the Table view, and tap the 4 PM column. easyTime instantly shows the equivalent time in every selected timezone, including exact minutes for zones with 30- or 45-minute offsets.
Does easyTime handle daylight saving time (DST)?
Yes. All timezone conversions use the browser’s built-in IANA timezone database, so DST changes are applied automatically for the exact date and time you are viewing — including the past and up to 7 days into the future.
Does this timezone calculator work offline?
Yes. easyTime is a fully client-side progressive web app (PWA). Once installed, it works with no internet connection, makes no API calls, and never sends your data anywhere.
Is easyTime free to use?
Yes, it is completely free, requires no account or sign-up, and works on any phone, tablet, or desktop browser.
