JST → PKTGap: -4h4h 9-5 overlap

JST to PKT currently uses Japan Time in Asia/Tokyo and Pakistan Time in Asia/Karachi as the live reference pair. Right now the gap is -4h, and the sections below break that into meeting-time shortcuts, workday overlap, DST changes, and city coverage on both sides.

Last updated Apr 22, 2026. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.

Pair context

JST and PKT currently connect Tokyo and Lahore with a live gap of -4h. Representative coverage on the JST side is anchored by Tokyo, Yokohama, Osaka, and Nagoya, while the PKT side is anchored by Lahore, Karachi, Peshawar, and Faisalabad.

Using a simple 9:00 AM to 5:00 PM workday on both sides, the pair shares about 4 hours of business overlap - roughly JST 1:00 PM previous day to 5:00 PM previous day, which is PKT 9:00 AM previous day to 1:00 PM previous day. There is still a usable shared block in the morning or afternoon, so teams can usually meet without pushing too far outside standard hours.

The live gap is -4h right now, based on Asia/Tokyo at +09:00 and Asia/Karachi at +05:00. Neither reference zone shows an offset change in the next year, so the gap should stay stable.

Market coverage on both sides

On the JST side, the current dataset is anchored by cities such as Tokyo, Japan; Yokohama, Japan; Osaka, Japan; Nagoya, Japan; Sapporo, Japan; Fukuoka, Japan. That makes this page useful for real-world coordination patterns rather than only abstract offset math.

On the PKT side, the live reference set includes Lahore, Pakistan; Karachi, Pakistan; Peshawar, Pakistan; Faisalabad, Pakistan; Rawalpindi, Pakistan; Gujranwala, Pakistan. In practice, that means the conversion is tied to recognizable business, travel, and support hubs rather than a single anonymous timezone label.

Country usage on the two sides currently includes Japan for JST and Pakistan for PKT. That country coverage helps explain why some pairs feel like outsourcing, logistics, gaming, finance, or travel-heavy conversions while others are more niche.

Operational notes

JST to PKT meeting times is easiest to read as a working-day range rather than a single spot conversion. In the current snapshot, 9:00 AM lands at 5:00 AM, while 9:00 PM lands at 5:00 PM, which makes the practical handoff window much easier to scan.

Overlap window and DST radar

The live gap is -4h right now, based on Asia/Tokyo at +09:00 and Asia/Karachi at +05:00. Neither reference zone shows an offset change in the next year, so the gap should stay stable.

The most usable workday block right now is about 4 hours: JST 1:00 PM previous day to 5:00 PM previous day, which lines up with PKT 9:00 AM previous day to 1:00 PM previous day.
