Calculate the number of days in a year

Is it possible to calculate the number of days in a year without having to put the year? If so how? Also i'm doing this on an m-file.

Answer 1

[Royi Avital]

I would go something like that:

firstDayInYear = '01/01/2012';
lastDayInYear = '31/12/2012';

firstDayInYearNum = datenum(firstDayInYear, 'dd/mm/yyyy');
lastDayInYearNum = datenum(lastDayInYear, 'dd/mm/yyyy');

numDaysInYear = lastDayInYearNum - firstDayInYearNum + 1;

That's it...

Answer 2

Or one of

    y = 2002;
    datenum([y+1,1,1]) - datenum([y,1,1])
    sum( eomday( y, [1:12] ) )
