About Timezone Converter

The timezone converter handles time translations between any IANA-registered timezones, automatically accounting for daylight saving time (DST) transitions and historical timezone changes. Essential for remote teams, international scheduling, travel planning, and global event coordination.

Timezone data comes from your browser's built-in Intl API, which uses the IANA timezone database maintained by the Internet Assigned Numbers Authority. This ensures accurate, up-to-date timezone rules including DST observances.

All conversions happen locally. No time data or scheduling information leaves your browser, ideal for confidential meeting planning or personal travel itineraries.

Frequently asked questions

DST is handled automatically using IANA timezone database rules. When you convert a time that falls during a DST transition, the converter applies the correct offset for that specific date.

Yes. Add multiple target timezones to compare times across regions simultaneously. Useful for finding meeting times that work across multiple offices or time zones.

The converter uses IANA timezone identifiers (e.g., "America/New_York" instead of "EST"). These are more precise because they encode DST rules and historical changes, not just current offsets.
