Frequently Asked Questions
How does the time zone converter work?
The time zone converter uses JavaScript Intl.DateTimeFormat to convert a given date and time from one time zone to another. It uses the IANA time zone database (e.g., America/New_York, Asia/Kolkata, Europe/London) to accurately calculate the equivalent time in the target zone, accounting for daylight saving time (DST) automatically.
Does the converter handle daylight saving time (DST)?
Yes, the converter automatically handles daylight saving time transitions because it uses the IANA time zone database built into JavaScript's Intl.DateTimeFormat. Regions that observe DST (like US Eastern Time, UK London, Europe Paris) are automatically adjusted based on the date you select.
What time zones are included?
This converter includes 34 carefully selected time zones covering all major regions worldwide. From UTC-12 (International Date Line West) through UTC+13 (Samoa), it includes major cities and regions: New York, London, Paris, Dubai, Mumbai (IST), Tokyo, Sydney, Auckland, and many more.
What is the time difference between India and the US?
India Standard Time (IST, UTC+5:30) is 9.5 hours ahead of US Eastern Time (ET, UTC-5) and 12.5 hours ahead of US Pacific Time (PT, UTC-8). During DST (March-November), the difference reduces by 1 hour: 9.5 hours ahead of EDT and 12.5 hours ahead of PDT.
What is the time difference between London and New York?
London (UTC+0/BST UTC+1) is typically 5 hours ahead of New York (UTC-5/EDT UTC-4). During winter (November-March), London is 5 hours ahead. During summer (March-October), when both observe DST, London is also 5 hours ahead because both clocks move forward simultaneously.
How do I use the UTC offset shown in zone names?
UTC offsets shown in parentheses (e.g., UTC+05:30) indicate the time difference from Coordinated Universal Time. Positive offsets are ahead of UTC (east), negative are behind (west). India (UTC+5:30) is 5 hours 30 minutes ahead of UTC, while US Eastern Time (UTC-5:00) is 5 hours behind.
Can I convert between any two time zones?
Yes, you can convert between any two time zones in our curated list. Simply select the source time zone and the target time zone, enter your date and time, and the converter shows you the equivalent time in the destination zone. This works for scheduling calls, meetings, or planning travel.
