Bengali Calendar বাংলা পঞ্জিকা
Traditional Bengali Panjika calculations remain lunisolar for religious dates, but the everyday civil Bengali calendar — reformed in Bangladesh in 1966 — runs on fixed month lengths, making it function much like a solar calendar day-to-day.
Lunisolar traditionally; the modern civil calendar (especially in Bangladesh) uses largely fixed solar month lengths

Worth knowing
The Bengali year count (Bangabda) is believed to trace back to Mughal-era solar-year administrative reform, which is why it runs roughly 593–594 years behind the Gregorian year rather than matching Vikram or Shaka Samvat.
This is one of several living regional calendar traditions across India, all ultimately related to the same Panchang principles. See the Hindu Calendar overview for how they connect, or The Sanskrit Calendar for the pan-Indian Panchang system this site covers in depth.
