If the autumn equinox falls on a Thursday in a non-leap year, on what day of the week will the same date fall exactly two years later (assuming neither year is a leap year)?
Saturday
A standard 365-day year equals 52 weeks plus 1 day (365 mod 7 = 1). Thus, each non-leap year shifts the day of the week forward by 1 day. In 2 non-leap years, the shift is 2 days: Thursday + 2 days = Saturday.
