What time is it in Karachi

Karachi is on Pakistan Standard Time, UTC+5, year-round. Phones should store Asia/Karachi. Clocks do not change for summer. This page shows sunrise, sunset, and weather on that hour. Karachi is the capital of Sindh and Pakistan’s main seaport on the Arabian Sea. It is not the national capital — that is Islamabad — but it gives its name to the country’s IANA zone. A clock in Lahore and a clock on the docks here show the same hour.

India Standard Time is thirty minutes ahead. China Standard Time is three hours ahead. São Paulo is eight hours behind, with a date change on many evening calls. Convert through UTC if you do not want the half hours to pile up.

A seaport that named the national zone

Asia/Karachi is the identifier phones should store for this city and, in ordinary civil use, for the rest of Pakistan. That does not make Karachi “the source” of Lahore’s hour in a legal sense. It makes the port the namesake of the database row. Humans can say Pakistan Standard Time. Programs should say Asia/Karachi.

Karachi lies west of Lahore, so the sun rises and sets later here on the shared wall clock. A dawn meeting that works on the Ravi can still be dark on the waterfront. Use this page’s sun table, not a Punjab copy, and not a Mumbai copy — Mumbai is a different country and a different offset.

Karachi to UTC: subtract five hours. Karachi to Mumbai: add thirty minutes. Karachi to Hangzhou or Wuhan: add three hours. Karachi to Mexico City: subtract eleven hours and write both dates. Port operations, flights, and markets all run on that single offset. A ship’s watch may still use UTC. If you are meeting a vessel, ask whether the time in the message is local or UTC. The harbour will not translate it for you. Sea breeze is not a second time zone. Karachi and Lahore already share the hour.

Coastal air versus the Punjab year

The Arabian Sea takes the edge off the inland extremes. Karachi is humid, with a sea breeze that Lahore does not get, and its winters are milder than Punjab’s. Heat still builds, especially when the wind fails. The monsoon can bring rain and low cloud, but the coastal year is not a copy of the Ravi plain.

Latitude is lower than Lahore’s, so the length of day changes less. You still should not reuse a June sunset in December. The table here is for this coast and this date. A listed sunrise behind monsoon cloud is still the astronomical sunrise; it is not a signal to wait for a second, unofficial dawn.

Humidity is the practical limit more often than darkness. An evening that still has legal daylight can feel heavy. A winter morning can be the cleanest outdoor window. Read the weather next to the clock. The offset only tells you which hour that forecast belongs to.

If you land at night from China, you have subtracted three hours and crossed into an earlier civil evening. If you land from São Paulo, you have added eight hours and often changed the date. Set the phone to Asia/Karachi before you treat a “local time” on the boarding pass as a guess. On this waterfront, local time is UTC+5.
