I already get it by year=cellfun(@(y) y(1:2),epoch,'uni',false); So i just need to convert day of year to month and date.Any suggestion on how to convert the terms after '.' to hours Any suggestions where I am going wrong? That would give you a date in the format you want. –gpalex Jul 13 '13 at 21:18 What have you tried so far - the reason I ask is If you would rather use the existing mktime functionality (recommended), which should most likely be present in the standard C library on any platform you are programming, my original answer content Day Of The Year Calculator

Why do aliens have higher tech than us? You may enter the year as a four-digit number or relative to 1900 (e.g. 97 will be assumed to be 1997, 110 will be assumed to be 2010). working good..though I don't need the year. You can also select a location **from the following** list: Americas Canada (English) United States (English) Europe Belgium (English) Denmark (English) Deutschland (Deutsch) España (Español) Finland (English) France (Français) Ireland (English)

I have the constructor Date2013(int dd). Days In A Year 2016 use POSIX; my **$dayNumber =** POSIX::strftime("%j", gmtime time); Replace time with other epochs for other days. Count the number of leap years (including the current year) since the base year (include the base year, if applicable).

It is not clear if your "epoch" is a CHAR matrix or a cell string. Rules for determining leap years A year is a leap year if It is evenly divisible by 4 BUT NOT evenly divisible by 100 UNLESS ALSO evenly divisible by 400. Thus there are only seven values of interest. How Many Days In A Year Divide the last two digits of the year by 12 with integer division, getting a quotient and a remainder.

In this member function I created an array with the months in it (January, February, Etc) Then I created an if statement that takes in dd, if dd falls in between It's basically a parlor trick that is completely useless, since it's hard to verify without a perpetual calendar (though such things are easily obtainable). greek alphabet Please counter-check the results. Compute the modulus-7 value of the sum of the numbers in steps 2-6.

So here's a modified algorithm that should be easier to keep in your head. To do this:daynum = sscanf(sprintf('%s*', day{:}), '%g*'); yearnum = sscanf(sprintf('%s*', year{:}), '%g*'); yearvec = zeros(numel(yearnum), 6); yearvec(:, 1) = yearnum; % [EDITED], no transpose yearvec(:, 1) = 1; % Perhaps also: or ... Therefore I do not think, that it does its work good here.You cannot simply mix the different approachs.
