About these times
Times come from your device clock and the IANA time zone database in your browser, so they follow each city's daylight saving rules automatically. The first row is your own time zone.
Why offsets change during the year
Cities that observe daylight saving move their offset by an hour twice a year, and do it on different dates in the Northern and Southern Hemispheres. Cities such as Mumbai, Tokyo, Dubai and Johannesburg keep a fixed offset. If you are planning a meeting, use the time zone converter for the exact date.
