Bangla Calendar is an Android application developed by Raha Softs in the Personalization category. The app provides users with a traditional Bengali and Georgian calendar that is mostly followed in Bangladesh, India, and Nepal. The calendar considers different rules before and after the year 1989 during the calculation. However, the app follows the rules from Bangladesh, which may differ from the Bangla calendar used in West Bengal, India.

Apart from the traditional calendar, the app has a moneybag manager and a currency converter. Users can donate and upgrade to the premium version of the app to get rid of ads. The app is free to use.

Overall, Bangla Calendar is a useful application for people who follow the traditional Bengali and Georgian calendar. The additional features of the app make it more practical. The app has a user-friendly interface and is easy to navigate. However, the app lacks customization options, which could be a disadvantage for some users.
