Why people convert India to Dhaka time
- Scheduling a call from India to Dhaka: a 10:00 AM start in India lands at 10:30 AM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both India and Dhaka are inside the 9-to-5 working day between 9:00 AM and 4:30 PM IST time (9:30 AM–5:00 PM BDST). That is roughly 7 hours 30 minutes of usable overlap.
- Coordinating a India-based team with Dhaka contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +0h 30m gap is not.
- Block 9:00 AM–4:30 PM IST as the recurring meeting window if you work primarily from India and need Dhaka colleagues present.
About IST (India Standard Time)
India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.
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.
