1) Dates are very, very, very hard. Calendar idiosyncrasies, time zones,
leap seconds... Be 100% sure you need to actually extend Date before
messing with it.
2) You are probably better off putting your method (presuming this is the
only one) in a custom utility class instead of extending Date so you don't
alter the functionality of any other libraries you use that aren't
expecting DOW to be non-standard.
getCustomDay(Date date) {
if (date.getDay() == 0)
return 7;
return date.getDay();
}
