About this converter

The Bengali (Bangla) calendar — বঙ্গাব্দ or Bangla Sambat (BS) — is a solar calendar used across West Bengal, Tripura, Assam, and Bangladesh. Its year begins on Pohela Boishakh, which falls on 14 or 15 April in the Gregorian calendar. This tool converts any Gregorian (English) date into its Bangla equivalent in a single click.

How the conversion works

For dates from Pohela Boishakh (mid-April) onward, the Bangla year is calculated as Gregorian year − 593. For dates from January until Pohela Boishakh, it is Gregorian year − 594. The 12 Bangla months — Boishakh, Jyaistha, Ashar, Shrabon, Bhadro, Ashwin, Kartik, Agrahayan, Poush, Magh, Falgun, and Choitro — each have fixed Gregorian start dates in the civil version used in Bangladesh.

Worked example

Take 23 May 2026. May falls after Pohela Boishakh, so the Bangla year is 2026 − 593 = 1433 BS. The Bangla month Jyaistha runs from 16 May to 14 June, so 23 May is the 8th day of Jyaistha. The full Bangla date is ৮ জ্যৈষ্ঠ ১৪৩৩ (8 Jyaistha 1433 BS).

Bangla numerals

The tool displays the day, month, and year in Bangla numerals (০ ১ ২ ৩ ৪ ৫ ৬ ৭ ৮ ৯) alongside the romanised form. This makes the result useful for both Bangla readers and anyone preparing bilingual documents.

Enter any Gregorian (English) date in the converter above and you will instantly see the Bangla calendar equivalent — the Bangla day, Bangla month name, and Bangla Sambat (BS) year, written in both Bangla numerals and romanised form.

What is the Bengali calendar (Bangla Sambat)?

The Bengali calendar (বঙ্গাব্দ / Bangla Sambat) is a solar calendar used in West Bengal, Tripura, Assam, and Bangladesh. The year begins on Pohela Boishakh (April 14 or 15 in the Gregorian calendar). The civil version used in Bangladesh fixes month lengths, while the West Bengal version follows traditional sidereal rules.

How is the Bangla year calculated from the English year?

For dates from Pohela Boishakh onward (mid-April to December), subtract 593 from the Gregorian year. For January to mid-April (before Pohela Boishakh), subtract 594. So 23 May 2026 falls in BS 1433, while 10 March 2026 falls in BS 1432.

What are the 12 Bangla months in order?

Boishakh (বৈশাখ), Jyaistha (জ্যৈষ্ঠ), Ashar (আষাঢ়), Shrabon (শ্রাবণ), Bhadro (ভাদ্র), Ashwin (আশ্বিন), Kartik (কার্তিক), Agrahayan (অগ্রহায়ণ), Poush (পৌষ), Magh (মাঘ), Falgun (ফাল্গুন), and Choitro (চৈত্র).
