The Bengali calendar, also known as the Bangla calendar, is a traditional calendar used in the Bengali-speaking regions of India and Bangladesh. It follows a 12-month lunar cycle and is based on the position of the moon relative to the constellations.

The Bengali calendar is used for both religious and cultural purposes and includes various festivals, auspicious dates, and holidays that are important to the Bengali-speaking community. Some of the major festivals celebrated in Bengali culture, such as Durga Puja, Kali Puja, and Poila Boishakh (Bengali New Year), are based on the Bengali calendar.

The Bengali calendar also includes information on tithis (lunar days), nakshatras (star constellations), yogas (planetary combinations), and karanas (half-tithis), which are important for determining auspicious times for various activities and events, such as weddings, housewarming ceremonies, and other rituals.

Today, the Bengali calendar is available in both print and digital formats, and several online resources offer free downloads of Bengali calendars. These calendars often include detailed information on auspicious dates, timings, and events specific to the Bengali community, making them a useful resource for people following Bengali traditions and culture.
