An important component of our advocacy work is observing certain national and international days, to both unite the indigenous communities of Sylhet Division and bring their issues to the attention of mainstream Bangla society.

Particularly for World Indigenous Day, we organize rallies and community meetings, and disseminate materials to mark these events.

ECDO observes the following days:

• International Mother Language Day (21 February)
• Independence Day (26 March)
• World Indigenous Day (9 August)
• Human Rights Day (10 December)
