- How to find days of any Calendar date of any year?
- First know this code for 20th century 144 025 036 146 ,
- easy to remember square of 12 , square of 5 , square of 6 and 146 !
- In the above code each digit represents a month ...starting from right ...1 for Jan, 4 for Feb, 4 for March...0 for April ...2 for may..5 for june...etc
- Then remember anothercode that is sunday =1, monday=2 , tuesday=3 etc ..till saturday = 0..
- Now, let us take the example :
- What day it was on 15/08/1947 ?
- Follow the below given steps :
- 1. write last two digits of the year ................... 47
- 2. no. of leap years till 1947 .....(47/4 = 11 take only quotient) = 11
- 3. write code of the month ...august (refer code) .......= 03
- 4. write the day.....................................15
- 5. add all the four ....47 + 11 + 03 + 15 = 76
- 6. divide the sum always by 7 = 76/7 and take the remainder. here the remainder is 6, now refer to the second code , 6 = friday. so, 15 /08/1947 was Friday !
- with little practice you will be able to calculate in mind...as you are doing simple addition and division!!!!!!! :)
- code for 21st century : 033 614 625 035
- How to write code for any century on our own?? >>
- for all future centuries, codes go on subtracting 1 from previous codes...& for all past centuries, codes go on adding 1.. so...future is -1, past is +1
- NOTE: If you subtract 1 from 0 we get 6 here...it is called MOD7
