A historical record is dated 3 July 2007. What was its weekday?

Correct answer: Option C — Tuesday. Counting total odd days up to this date, or using a verified Gregorian calendar calculation, gives weekday index 1 where Monday is 0; therefore the day is Tuesday. Option A (Wednesday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (Thursday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (Saturday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.
