Time Zone Converter
Convert times between any two time zones with full daylight saving support. Free, instant.
Why Time Zone Conversion Matters
Remote work and global teams make time zone conversion a daily need. A meeting scheduled for 9 AM in New York is 2 PM in London and 10:30 PM in Mumbai — and those offsets shift by an hour twice a year when countries observe daylight saving time. Getting it wrong means missed meetings, delayed responses or frustrated clients. This converter handles all DST transitions automatically using the IANA timezone database, so you always get the correct local time regardless of the date.

Daylight Saving Time (DST)
Many countries shift their clocks forward by one hour in spring and back in autumn. The transition dates vary by country — the US and Canada change on the second Sunday in March, while most of Europe changes on the last Sunday in March. This means the offset between two time zones can change by one hour depending on the date. This converter accounts for DST automatically by using the full IANA timezone identifier (e.g. America/New_York) rather than a fixed UTC offset.
Tips for Scheduling Across Time Zones
- Use UTC for server logs and APIs — always store timestamps in UTC and convert to local time only for display.
- Note the date when crossing midnight — 10 PM in New York on Monday is 3 AM in London on Tuesday.
- Avoid scheduling on DST transition days — clocks change at 2 AM, creating a 23- or 25-hour day that can cause scheduling confusion.
