Create month array?

Hello,

Is it possible to create a datetime array with just entries from January to December?

I tried it like this but it did not work:

str = (1:12);
t = datetime(str(:),'InputFormat','mm');

I just want an array with 12 entries and each of them is a month with datatype "datetime"

D = datetime(2021,1,1):calmonths(1):datetime(2021,12,31)

D = 1×12 datetime array
   01-Jan-2021   01-Feb-2021   01-Mar-2021   01-Apr-2021   01-May-2021   01-Jun-2021   01-Jul-2021   01-Aug-2021   01-Sep-2021   01-Oct-2021   01-Nov-2021   01-Dec-2021

D.Format = 'MMM'

D = 1×12 datetime array
   Jan   Feb   Mar   Apr   May   Jun   Jul   Aug   Sep   Oct   Nov   Dec

Hello,

Is it possible to create this datetime array independent of the year (i.e. 2021 in this example)?

Thanks.

"Is it possible to create this datetime array independent of the year (i.e. 2021 in this example)?"

The DATETIME object has a YEAR property which always has some value assigned to it: if you do not assign a value to it, then the object construction will use some default value. Also due to the fact that years have different lengths (leap years, leap seconds) the exact time at the start of each month in a year can only be determined once the year has been specified. Because DATETIME objects encode exact times, the DATETIME object must specify the year.

What do you plan on doing with such an array?

year = 2020 ; 
t = datetime(year,1,1):dateime(year,12,31) ;
