BanglaConverter would not exist without the work below. Each entry names the author and the licence the work is used under.
The Bijoy ⇄ Unicode mapping tables and conversion routines come from the bnwebtools project by S M Mahbub Murshed, used under the GNU General Public License. The original copyright and licence notice is preserved in the JavaScript we serve, and that JavaScript is the source form — you can read it directly at /assets/converter-js/.
The Bijoy-style fixed keyboard layout used by the Unicode editor is derived from the m17n database's bn-unijoy input method, used under the GNU Lesser General Public License.
Phonetic typing follows the scheme popularised by Avro Keyboard from OmicronLab. Our implementation is independent; we are not affiliated with OmicronLab.

Bangla, Hijri and Gregorian dates are computed from published calendrical algorithms. Prayer times are calculated astronomically for the district you select and may differ by a minute or two from your local mosque, which is the authority to follow.
