Thanks to torkona for providing the bengali version of the G.O. published in the B.B. Kundu & Sons. compilation.
Thanks to mihiracharya for posting the english version of the instruction on 13 Sept, 2012, which is as follows:

1) There was arisen the same question from the Headmaster, Talpur Pathsala ,P.O.- Talpur, Dt. Hooghly, on his letter no. 30/80 dated 22.04.80.
In reply dated 11.07.80 in behalf of WBBSE, the secretary, A. Gupta clarified that “Holidays declared by the Govt. of West Bengal and by the Govt. of India the N.I.Act or by any competent authority may be regarded as ‘Special Holidays’ in addition to the approved holidays in a year.”
That means the holidays of N.I.Act is/are the extra holidays of 65 days holidays.
2) There is no circular. A list is published by the board.That may be taken as Model. The list of the holidays is made by the H.M with the consult of the M.C. The School Authority may allow HOLIDAYS on local demand (festivals). Thank you.

I feel sorry to say that insertion of phrase ‘in the currency of the relevant year’ in the original version would remove the confusion if it is stated in the following manner:
“Holidays declared by the Govt. of West Bengal and by the Govt. of India under the N.I.Act or by any competent authority in the currency of the relevant year may be regarded as ‘Special Holidays’ in addition to the approved holidays in a year.”

Such holidays declared under N.I. Act during a year i.e. after taking effect of APPROVED holiday list are always SPECIAL not only to the teachers but also to the govt. employees who enjoy them IN ADDITION TO the enlisted N.I. Act holidays approved before inception of the year. 26th Jan., 15th Aug., 2nd Oct. etc. are all holidays declared under N.I. Act, but they are neither SPECIAL nor EXTRA/ADDITIONAL holidays as they are already included in the APPROVED holiday list. On the other hand, some times 14th April is declared as public holiday under N.I. Act in the CURRENCY of the year on account of Ambedkar’s Birthday i.e. holiday declared after taking effect of the approved N.I. Act holidays (enlisted holidays) in govt. offices. In this particular case, this is special/extra holiday for govt. employees.
