Find out on which day you were born?

Have you ever wondered which day of week you were born? I guess yes! So lets find out using simple math to find the day of the week on which you were born.
Finding the month number!
We know that January has 31 days. A week has 7days so every date in February will be 3 days later than the same day in January. (28 is 4 weeks exactly. 28+3=31). For instance, if January 1st of any given year falls on Saturday, February 1st of that year will be 3 days later. That is on Tuesday. Following the same pattern for all the months, the following table is calculated.
Jan: 0, Feb: 3, Mar: 3, Apr: 6, May: 1, June: 4, July: 6, Aug: 2, Sept: 5, Oct: 0, Nov: 3, Dec: 5
The Process
Step 1- Write down your date of birth. Let us say 12th March 1983.
Step2- Number associated with the month from the above table is 3 .
Step 3- Write down the date , 12.
Step 4- Write down last two digits of the year, 83.
Step 5- Let us find out the number of leap years. Divide the last two digits of the year by four. 83/4=20 remainder 3.
Step 6- Now add all the four numbers from Step 2 to Step 5. 3+12+83+20=118.
Step 7- Divide 118 by 7 = 16 Remainder 6. Remainder tells you the day.
For finding out the day, refer to the following table:
Sunday: 0
Monday: 1
Tuesday: 2
Wednesday: 3
Thursday: 4
Friday: 5
Saturday: 6
From above, 6 is associated with Saturday so the answer is Saturday.
If you know any other method to find the day of a given date, you are most welcome to share with us.
