World Clock and Day-Night Map
Day and night zones, GMT lines and city timesNatural Earth public-domain geography; boundaries are illustrative and not a statement of territorial claims. Equirectangular projection: shapes and areas distort toward the poles. Shading shows approximate sunlight, not cloud cover.

Reading world time from India
India stays at UTC+5:30. New York and London can change their offsets seasonally, while Dubai stays at UTC+4. A country name alone is not always a timezone: the USA spans several. Use the India-USA, India-UK and India-UAE guides for practical examples, or select a date in the IST converter.
A day-night map shows approximate sunlight, not working hours or political timezone boundaries. Local dates can differ across the map even at the same instant. The live display depends on your device clock; check device time settings if the clock is wrong.
