Date: Take the day of the month = 25
Year: Take the last two digits of the year = 26
Leap Year Code: Divide the last two digits by 4 (ignore remainder) = $26 / 4 = \mathbf{6}$
Month Code: For April, the code is 6
Century Code: For the 2000s, the code is 6
Total Sum:
$$25 + 26 + 6 + 6 + 6 = 69$$
Find the Remainder:
Divide the total by 7 (the number of days in a week):
$$69 \div 7 = 9 \text{ with a remainder of } \mathbf{6}$$
Final Result:
A remainder of 6 corresponds to Saturday.
