Bangladesh's 2027 government holiday list had not been published as of 31 October 2026; the 14 April date comes from the revised calendar's rule.

Why the two Bengals differ

In 1966 a committee led by Muhammad Shahidullah revised the Bengali calendar, and Bangladesh adopted it officially in 1987, so Pohela Boishakh there is always 14 April. West Bengal and Tripura follow the traditional panjika, so the day falls on 14 or 15 April. (Source: Wikipedia, Pohela Boishakh)
