Why people convert BDST to Argentina time

Scheduling a call from BDST to Argentina: a 10:00 AM start in BDST lands at 1:00 AM in Argentina, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h gap: BDST and Argentina have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Argentina is 12:00 AM in BDST.

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.
