Colombo to Dhaka Time

Colombo (Sri Lanka) is a South Asian island economy with strategic Indian Ocean positioning, with key industries in tourism, tea, apparel, and IT/BPO services. Dhaka (Bangladesh) is a rapidly industrializing economy and garment export powerhouse, known for garment manufacturing, pharmaceuticals, IT services, and remittances. With a 0.5-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.

Scheduling Meetings Between Colombo and Dhaka

With only a 0.5-hour gap, Colombo and Dhaka have generous overlapping work hours. Morning calls in the later time zone align well with mid-day in the other.

Most teams find that late morning to early afternoon offers the widest window for collaboration.
