Time Zone Converter

How to Use Time Zone Converter

1. Select the date and time using the datetime picker (defaults to your current local time).
2. Choose the source and target time zones from the searchable dropdowns — type part of a city name to filter.
3. Use the quick‑pair buttons (IST→EST, IST→GMT, etc.) for common conversions, or swap zones with the ⇄ button.
4. Read the converted date/time and the hour difference. The tool uses Intl API to automatically handle DST changes — no manual adjustments needed.

Frequently Asked Questions

How does the tool handle Daylight Saving Time?

It uses the browser’s built‑in Intl.DateTimeFormat API, which is kept up to date with global DST rules. You simply pick the zones, and the offset is calculated automatically.

What is the difference between IST and EST?

IST is UTC+5:30 year‑round. EST is UTC−5:00 in winter and EDT (UTC−4:00) in summer. The converter shows the correct difference for any date you select.

Can I use this for scheduling a recurring weekly meeting?

Yes, but check DST transition weeks. The tool is great for one‑off conversions; for recurring invites, use the converted times to set the meeting in your calendar.

Is Time Zone Converter free and private?

Yes — it is 100% free, needs no sign-up, and everything runs in your browser; your data never leaves your device.
