- Official government and public holidays for 2026
- Daily prayer (Namaz) times for major cities across Bangladesh
- Ramadan 2026 Sehri and Iftar timetables
- National, cultural, and Islamic event listings

Use of AI & Automation
Some content on this site — including textual descriptions, holiday summaries, and editorial copy — is generated or assisted by artificial intelligence (AI) tools, including large language models (LLMs). AI-generated content is reviewed and edited by our team before publication, but users should treat it as informational rather than authoritative.
Calendar calculations (date conversions, prayer times, astronomical data) are performed by deterministic algorithms — not by AI — to ensure accuracy.
If you notice an error in any AI-assisted content, please contact us so we can correct it promptly.
Data Sources
Our data is compiled from reliable public and governmental sources. See our dedicated Sources page for the full list. Key references include:

Accuracy & Disclaimer
While we strive for accuracy, date conversions, prayer times, and event listings are provided for informational purposes only. Official government announcements and local mosque timings should always be considered the final authority. Bangladesh Calendar is an independent project and is not affiliated with any government body or religious institution.
Behind the Project
Bangladesh Calendar is maintained by a small independent team passionate about making Bangla and Islamic calendar information freely accessible online. The project is non-commercial and funded solely through display advertising.
