Why people convert Dhaka to Sydney time

- Finding shared working hours: both Dhaka and Sydney are inside the 9-to-5 working day between 9:00 AM and 1:00 PM BDST time (1:00 PM–5:00 PM AEST). That is roughly 4 hours of usable overlap.
- Watching a live event or market open: Dhaka viewers need 1:00 PM in Sydney to catch a 9:00 AM start there, and 8:00 PM if the event is anchored to Dhaka.

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 AEST (Australian Eastern Standard Time)
Australian Eastern Standard Time (AEST) is used in the eastern states of Australia including New South Wales, Victoria, Queensland, Tasmania, and the ACT. During summer (October to April), NSW, VIC, TAS, and ACT switch to Australian Eastern Daylight Time (AEDT, UTC+11:00), while Queensland remains on AEST year-round.
