About BDST (Bangladesh Standard Time)
Bangladesh Standard Time (BDST) is the single time zone used across Bangladesh, fixed at UTC+06:00 all year. Bangladesh has not observed daylight saving time since a short-lived experiment in 2009, so the gap between Bangladesh and every other zone is constant. Dhaka, the capital, is one of the most densely populated cities in the world. Because the country sits close to the middle of the UTC+06:00 band, solar noon is near 12:00 for most of the year. BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.
About WET (Western European Time)
Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).

Business hours overlap
BDST and Lisbon overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.
