Last Sunday in a month?

Hi there,

I am trying to identify the datetime of the last Sunday in March and October. I am aware of the nweekdate function but it requires the nth occurence of the day in that month, as an input. Any ideas would be highly appreciated.

Thank you in advance,

Andreas

d = calendar(2013,01) ;
s = d(d(:,1)~=0,1)
s(end)

Unless you are using a version of MATLAB prior to R2014b, use datetimes for dates, not numbers:

>> d = dateshift(datetime(2018,[3 10],1,'Format','eee, dd-MMM-yyyy'),'end','month')
d = 
  1×2 datetime array
   Sat, 31-Mar-2018   Wed, 31-Oct-2018
>> d = dateshift(d,'dayofweek','sunday','previous')
d = 
  1×2 datetime array
   Sun, 25-Mar-2018   Sun, 28-Oct-2018
