CENTURY CODE

• 1700 - 4
• 1800 - 2
• 1900 - 0
• 2000 - 6
• 2100 - 4
• 2200 - 2
• 2300 - 0

MONTH CODE

• JANUARY - 1
• FEBRUARY - 4
• MARCH - 4

DAY CODE

• SUNDAY - 1
• MONDAY - 2
• TUESDAY - 3
• WEDNESDAY - 4
• THURSDAY - 5
• FRIDAY - 6
• SATURDAY - 0

Let us take an example. The date considered is January 27,2008.
1. Take the last two digits of the year and divide the number by 4, drop the remainder.

     8 / 4 = 2

2. Add the day of the month to that number.

     27 + 2 = 29

3. Add month code to the answer. Refer above for the month code.

     29 + 1 = 30

4. Add century code to it. Refer above for the century code.

     30 + 6 = 36

5. Take the result. Add last 2 digits of the year.

     36 + 8 = 44

6. Divide the number by 7. Take only the remainder.

     44 / 7 = Quotient is 6, Remainder is 2

7. Refer to the day code above. Since the remainder is 2, the day is MONDAY

So, JANUARY 27,2008 is a MONDAY.

Check it with any date of your choice!!!!!.
