How It Works

The converter uses standard month transition dates for the Bengali calendar (based on the revised Bangla Academy calendar used in West Bengal). Each Bengali month starts on a fixed Gregorian date, and the Bengali year is calculated by subtracting 593 or 594 from the Gregorian year depending on the month.

Formula

Bengali Year = Gregorian Year − 593 (after Chaitra/আশ্বিন) or − 594 (before Ashadha) | Month determined by Gregorian date ranges
