§ 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 another
code 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.
