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 */ }
