What It Does

Timezone Converter lets you instantly translate a time from one timezone to another. Select a source timezone and time, choose your target timezone, and see the result. Live clocks show current time in each zone, and a swap button lets you reverse the conversion direction.

Common Timezone Reference

  • UTC — Coordinated Universal Time (no offset)
  • America/New_York — EST (UTC−5) / EDT (UTC−4)
  • America/Los_Angeles — PST (UTC−8) / PDT (UTC−7)
  • Europe/London — GMT (UTC+0) / BST (UTC+1)
  • Europe/Berlin — CET (UTC+1) / CEST (UTC+2)
  • Asia/Kolkata — IST (UTC+5:30, no DST)
  • Asia/Tokyo — JST (UTC+9, no DST)
  • Australia/Sydney — AEST (UTC+10) / AEDT (UTC+11)

Scheduling Across Time Zones

When scheduling international meetings, pick a time that falls within business hours for all participants. A common overlap window is 8–10am Pacific / 11am–1pm Eastern / 4–6pm London / 5–7pm Berlin — though this breaks down once Asia-Pacific is included.

Tips

Always double-check times around DST transition dates (second Sunday in March and first Sunday in November for US zones). Scheduling at exactly the transition hour can result in a 1-hour error if DST is not accounted for correctly.

Frequently Asked Questions

How do I convert a meeting time across multiple timezones?
Enter the meeting time in your local timezone, then select the target timezone to see what time it corresponds to. You can swap source and target with the swap button to check the inverse.
What is the difference between UTC offset and a named timezone?
A UTC offset like UTC+5:30 is a fixed difference from UTC. A named timezone like America/New_York adjusts automatically for daylight saving time (DST), so the actual offset changes throughout the year. Use named timezones when scheduling across DST boundaries.
Does this tool account for daylight saving time?
Yes. The converter uses the IANA timezone database via the browser's Intl API, which automatically applies DST rules for the selected date and timezone.
What are the most commonly confused timezone pairs?
EST vs EDT (US Eastern Standard vs Daylight), IST (India Standard vs Israel Standard vs Irish Standard), and CST (US Central vs China Standard) are frequently confused. Always verify the full IANA timezone name when scheduling international meetings.
What is UTC and why is it used as a reference?
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It has no DST offset and does not change seasonally, making it the reliable reference point for converting between all other timezones.
