You can do it using formula fiel like this


CASE( MOD( date - DATE( 1900, 1, 7 ), 7 ), 0, "Sunday", 1, "Monday", 2, "Tuesday", 3, "Wednesday", 4, "Thursday", 5, "Friday", 6 ,"Saturday" )


Note that this formula only works for dates after 01/07/1900. If you’re working with older dates, use the same process with any Sunday prior to your earliest date (e.g. 01/05/1800).
You can also adjust this formula if your week starts on a different day. For example, if your week starts on Monday, you can use January 8, 1900 in your condition. The new formula looks like this:


or you can us the same in apex code like this

date StartDate = date.newInstance(1900, 1, 8);
date Todaydate = system.today();
Integer numberDaysDue = startDate.daysBetween(Todaydate);
Integer x = math.MOD( numberDaysDue , 7 );

system.debug('$!@%#$!@%#'+ x);

like it return 1 as its tuesday
