The aforementioned announcement of the official non-working public holidays in Bangladesh for 2013 (DFIM Circular No. 09. 29/11/12) contains a few odd dates, in particular, and once again (2012-01-01), the date stated for the Buddha Purnima (Baishakhi Purnima) public holiday is listed a 2 days earlier than one would have expected (and which is listed by the governments of India and Sri Lanka).
This date for the 2013 Buddha Purnima in Bangladesh will probably be amended at a later date as was done for the corresponding 2012 date of Buddha Purnima (2012-05-02).
