Time Zone Converter

Key features

• 75 curated IANA zones — from America/Los_Angeles to Asia/Kolkata to Pacific/Auckland — plus your device's own zone pinned at the top.
• Daylight saving handled by the browser's IANA database for the exact date, with an on-page note when DST is active at the destination.
• Half-hour and 45-minute offsets (India, Nepal and friends) display correctly as UTC+05:30-style badges.
• A day-shift badge tells you when the conversion lands on a different calendar day.
• A world-glance row for New York, London, Dubai, Tokyo and Sydney, each with its own day difference.
• 12/24-hour toggle, exact UTC instant readout and a copyable summary.

How it works

1. 1

   Set the moment

   Enter a date and time, or hit Now to load the current minute.

2. 2

   Pick the zones

   Choose From (your own zone is pre-selected) and To from the curated list; the swap button reverses them.

3. 3

   Read the converted time

   The destination's time, weekday and date appear with a Same day / ±N days badge.

4. 4

   Check the context

   Offset badges for both zones, the UTC instant, DST notes and the five-city world glance complete the picture.

5. 5

   Copy the summary

   One line like “2025-01-10 09:30 (America/New_York) → 15:30 (Europe/Paris)” — great for calendar invites.

Tips for better results

• 💡For meetings, convert the other city's working hours back to yourself and look for the overlap — the world-glance row makes the scan instant.
• 💡Watch the day-shift badge when scheduling late calls: a +1 day means the meeting is “tomorrow” for them.
• 💡Offsets are computed per date, so a January meeting and a July meeting in London can correctly differ by an hour.
• 💡Zones use IANA names (continent/city) rather than abbreviations like EST — abbreviations are ambiguous, IANA names aren't.
