I do not really understand your question. Perhaps if you write what you expect we can tell you a function or anything else.
Do you want the name of the months? Then it would be FormatDateTime('mmmm', aDate);

See: https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html

Code: Pascal  [Select][+][-]

1. WriteLn(FormatDateTime('dddddd', now)); // ---> Tuesday, May 16 2017
2. //or:
3. WriteLn(FormatDateTime('dddd', now);    // ---> Tuesday

"Now" returns the current date and time. For any other date use the function EncodeDate():

Code: Pascal  [Select][+][-]

1. var
2.   d: TDate;
3. begin
4.   d := EncodeDate(2017, 3, 17);
5.   WriteLn(FormatDatetime('dddd', d));
6.

Is the DayOfWeek function from the DateUtils what you need?

function DayOfWeek(DateTime:TDateTime): integer;
