In a govt. aided school while calculating gross salary for TDS, salary for march of last year (last Previous Year say 2011-2012) is included in gross salary (  say salary for march 2012 paid in april 2012) and salary for current year last month ( march 2013) is excluded as salary for march 2013 paid in April 2013.i.e gross salary is taken 12 months from March 2012 to Feb 2013.

Please let me know is this correct? can they do it saying salary becomes due on 1st day of next month? it is neither paid nor due in the current year as far as salary for march is concerned.
