I noticed that there are several days in use as “Tagore’s Birthday”, which is an official holiday in Bangladesh. This year, 2003, the official Bangla day was 9 May, but 7 and 8 May are also in use.
It’s because the date according to the Bangla calendar can cause a little defection from the Western one, as his birthday was 25 Baishakh 1268. Which corresponds with 7 May 1861 on the Western calendar.
