If you work with remote teams, schedule international meetings, or just want to know what time it is in Dubai when it’s 3 PM in Hyderabad — manually calculating timezone differences is exhausting and error-prone. Our free world timezone converter solves this with a beautiful visual timeline, just like WorldTimeBuddy, completely free and without any sign-up.
What Is a Timezone Converter?
A timezone converter is a tool that lets you see the equivalent time in multiple cities or countries simultaneously. Instead of doing mental arithmetic about UTC offsets — “IST is UTC+5:30, EST is UTC-5, so the difference is 10 hours and 30 minutes…” — a timezone converter shows you everything visually at a glance.
The world has 38 distinct UTC offsets, including half-hour and quarter-hour offsets (like India’s UTC+5:30 and Nepal’s UTC+5:45). A good timezone converter handles all of these correctly, including daylight saving time changes that shift clocks by 1 hour in countries like the USA, UK and most of Europe.

How to Use the Timezone Converter
Step 1 — Start with Presets
The fastest way to get started is clicking one of the preset buttons at the top. These are pre-configured for the most common timezone comparisons:
- 🇮🇳 IST ↔ 🇺🇸 EST — India (Mumbai) + New York + London. Perfect for Indian developers working with US East Coast clients.
- 🇮🇳 IST ↔ 🇺🇸 PST — India + Los Angeles + Tokyo. For teams working with US West Coast or Japan.
- 🇮🇳 IST ↔ 🇦🇪 GST — India + Dubai + Singapore. The Gulf/South Asia corridor.
- 🌏 APAC — Tokyo + Singapore + Sydney + Mumbai. For Asia-Pacific regional teams.
- 🌍 Europe — London + Paris + Berlin + Moscow. For European teams.
- 🌐 Global HQ — London + New York + Dubai + Singapore + Tokyo. The 5 major financial hubs.
Step 2 — Add Custom Cities
Type any city name or timezone in the search box at the top and click + Add to add it to your timeline. The tool supports 100+ cities and all IANA timezone identifiers. You can add as many cities as you need — they stack as horizontal rows in the timeline grid.
Step 3 — Read the Timeline Grid
The main timeline grid shows 24 hours across all your selected cities. Each row represents one city. The colour coding helps you instantly understand availability:
The red NOW line shows the current moment for each city. Click any hour cell to see that exact time across all your added cities in a summary panel below the grid.
Step 4 — Use the Quick Converter
Scroll down to the Quick Converter section. Select a source city from the dropdown, type a time, select the destination city, and the converted time appears instantly. This is perfect for answering questions like “What is 2 PM IST in PST?” without doing any maths.
Step 5 — Share Your Setup
Click the 🔗 Share button to copy a shareable URL that encodes your exact city selection. Send this link to your team and everyone opens the same timezone comparison. No account needed.

IST to Other Timezones — Quick Reference
India Standard Time (IST) is UTC+5:30. Here is how IST compares to all the major world timezones:
Tips for Scheduling International Meetings
- Find the overlap: Use the green (working hours) bands in the timeline to visually identify when all participants are in their working day simultaneously — this is the ideal meeting window.
- Avoid the red zone: Any city showing grey (night) or amber (very early morning) should not be scheduled without explicit consent from that team member.
- Account for DST: Daylight saving time shifts by 1 hour in the US (March–November), UK and Europe (March–October) and Australia (October–April). Our tool uses live timezone data so it always shows the correct current offset.
- Use the shareable link: When agreeing a meeting time, share the link from our tool so everyone sees the same reference — no ambiguity about whose timezone you mean.
- India has no DST: IST is always UTC+5:30, year-round. This means the IST–EST difference changes by 1 hour when the US observes DST (it goes from 10.5 hrs to 9.5 hrs during US summer).
