Current time in Dadra and Nagar Haveli and Daman and Diu, India

Daman, Diu, Silvassa, Dadra, and every smaller settlement in the union territory share IST. The geographically separated districts do not have separate time zones, and none observes daylight saving time.

The present union territory combines areas on or near India’s western side. Administrative separation and stretches of intervening land do not affect civil time: the national standard governs each component. The territory comes in separate pieces, but its clocks arrive fully assembled.

One zone across several districts

IST is five hours and thirty minutes ahead of UTC. Its offset remains unchanged throughout the year. A calendar event defined in local time therefore keeps the same UTC relationship, provided it is explicitly associated with IST.

Time standard: Indian Standard Time Common abbreviation: IST Offset: UTC+5:30 Daylight saving time: not observed Internal official time boundaries: none To convert a UTC time, add five hours and thirty minutes. For an event involving another country, examine that location’s rules on the specified date. Any seasonal shift in the time difference comes from the other zone, not this union territory.

Principal centres and coastal daylight

Daman and Silvassa are principal administrative and urban centres. Diu is the main town on Diu Island, while Dadra and Naroli are among the settlements in the inland district. Since the components differ in size and character, a single ranking of “largest cities” may conceal more than it explains.

Local sunrise varies among Daman, Diu, and Silvassa despite their shared clocks. Longitude, latitude, date, and horizon determine solar times. Diu lies farther west than the inland district, so equivalent solar events are generally later by IST there, with seasonal and geographic qualifications.

For a coastal viewpoint, an open horizon may make the calculated event easier to observe. Inland, hills, trees, or buildings may delay visible sunlight. Cloud and haze affect visibility but do not change the astronomical calculation.

Pick the correct district and settlement. Check the local calendar date. Read dawn and sunrise as separate events. Use the immediate horizon when planning photography or travel.

They form a single union territory containing distinct districts and geographically separated areas.
