ICT → BSTGap: -1h7h 9-5 overlap

ICT to BST currently uses Indochina Time in Asia/Ho_Chi_Minh and Bangladesh Time in Asia/Dhaka as the live reference pair. Right now the gap is -1h, 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.

Ambiguity note

BST is ambiguous in this dataset, so the live converter uses Asia/Dhaka as the busiest reference zone while the city list below shows the wider label family.

Pair context

ICT and BST currently connect Ho Chi Minh City and Dhaka with a live gap of -1h. Representative coverage on the ICT side is anchored by Ho Chi Minh City, Hanoi, Bangkok, and Haiphong, while the BST side is anchored by Dhaka, Chattogram, Gazipur, and Khulna.

Using a simple 9:00 AM to 5:00 PM workday on both sides, the pair shares about 7 hours of business overlap - roughly ICT 10:00 AM previous day to 5:00 PM previous day, which is BST 9:00 AM previous day to 4:00 PM previous day. Most of the workday still lines up, which is helpful for live support, same-day reviews, and straightforward calendar invites.

The live gap is -1h right now, based on Asia/Ho_Chi_Minh at +07:00 and Asia/Dhaka at +06:00. Neither reference zone shows an offset change in the next year, so the gap should stay stable.

Market coverage on both sides

On the ICT side, the current dataset is anchored by cities such as Ho Chi Minh City, Vietnam; Hanoi, Vietnam; Bangkok, Thailand; Haiphong, Vietnam; Phnom Penh, Cambodia; Cần Thơ, Vietnam. That makes this page useful for real-world coordination patterns rather than only abstract offset math.

On the BST side, the live reference set includes Dhaka, Bangladesh; Chattogram, Bangladesh; Gazipur, Bangladesh; Khulna, Bangladesh; Rangpur, Bangladesh; Comilla, Bangladesh. 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 Vietnam, Thailand, and Cambodia for ICT and Bangladesh and Papua New Guinea for BST. 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

ICT to BST 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 8:00 AM, while 9:00 PM lands at 8:00 PM, which makes the practical handoff window much easier to scan.

BST to ICT 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 10:00 AM, while 9:00 PM lands at 10:00 PM, which makes the practical handoff window much easier to scan.

Overlap window and DST radar

The live gap is -1h right now, based on Asia/Ho_Chi_Minh at +07:00 and Asia/Dhaka at +06:00. 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 7 hours: ICT 10:00 AM previous day to 5:00 PM previous day, which lines up with BST 9:00 AM previous day to 4:00 PM previous day.
