Karachi uses Pakistan Standard Time (PKT, UTC+5) year-round. Pakistan does not currently observe Daylight Saving Time (it was briefly reintroduced in 2008 but discontinued). The fixed UTC+5 places Karachi and Lahore thirty minutes behind IST and one hour ahead of Dubai.
Sydney uses Australian Eastern Standard Time (AEST, UTC+10) in winter and Australian Eastern Daylight Time (AEDT, UTC+11) in summer. Because Australia is in the Southern Hemisphere, its summer runs October–April — the opposite of the Northern Hemisphere. Clocks go forward on the first Sunday of October and back on the first Sunday of April.
Both Karachi and Sydney may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | Karachi | Sydney | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | GMT+5 (UTC+5) | GMT+11 (UTC+11) | 6 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | GMT+5 (UTC+5) | GMT+11 (UTC+11) | 6 hours |
| Late Mar – Oct current | Both on summer / daylight time | GMT+5 (UTC+5) | GMT+10 (UTC+10) | 5 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | GMT+5 (UTC+5) | GMT+11 (UTC+11) | 6 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
