The noun 'weekdays' is the plural form. The singular noun is weekday.
One way to determine the day of week based on the date is to use Zeller's congruence. For the Gregorian calendar... int dayofweek (int month, int day, int year) { int weekday; if (month < 3) month += 12; weekday = day; weekday += int ((month + 1) * 26 / 10); weekday += year; weekday += int (year / 4); weekday += 6 * int (year / 100); weekday += int (year / 400); weekday %= 7; return weekday; /* 0 = Sunday, ..., 6 = Saturday */ }
The "at" is superfluous.
