How to Convert Time Zones Correctly

Every timezone is defined relative to Coordinated Universal Time (UTC). UTC never observes Daylight Saving Time and never changes. Our converter uses the IANA timezone database to automatically account for DST transitions.

The primary complication in timezone conversion is Daylight Saving Time (DST). The US shifts on the second Sunday of March, while the EU shifts on the last Sunday of March, briefly creating unusual offsets between those dates. Always verify the date, not just the time, when scheduling across large timezone differences.

Frequently Asked Questions

How do I convert EST to IST?▾

EST (UTC−5) and IST (UTC+5:30) differ by 10.5 hours — IST is ahead. 9:00 AM EST = 7:30 PM IST. During EDT (UTC−4) the gap shrinks to 9.5 hours.
Does DST affect timezone conversions?▾

Yes. When the US observes EDT the offset to non-DST countries changes by an hour. Our converter handles this automatically.
What is the time difference between New York and London?▾

Typically 5 hours (London ahead). During the 2-week DST window mismatch in March it becomes 4 hours temporarily.
