★★what is the formula or how to calculate which day on this day★★

✔✔for example which day on the date 18/9/2005✔✔

Answer

Given , 18/09/2005

$\leq Step :- 1\geq$

• Have a look at the given year What do you think is it leap year or non-leap year
• Let us find take last 2 digit of the year 2005
• " 05 " Divide it by 4 is it divisible { NO }
• That means 2005 not a leap year
• Hence , leap year = 0

$\leq Step :-2\geq$

• Now , let us look at century
• Century is 2000
• Here we have some codes for Centuries
• The codes  are as follow :-

=>  $\left[\begin{array}{ccc}1600&&6\\1700&&4\\1800&&2\end{array}\right]  \left[\begin{array}{ccc}1900&&0\\2000&&6\end{array}\right]$

• According to that code we have to put  6 in place of  2000 Century

$\leq Step :- 3 \geq$

• Now , let us focus about months ; There are 12 months in a year
• Given , month = 09 (  i.e.  September  )
• Also , for months there are some codes as follow :-

 $\left[\begin{array}{ccc}Jan&&1\\Feb&&4\\March&&4\end{array}\right]$ $\left[\begin{array}{ccc}April&&0\\May&&2\\June&&5\end{array}\right]$

$\left[\begin{array}{ccc}July&&0\\Aug&&3\\Sept&&6\end{array}\right]  \left[\begin{array}{ccc}Oct.&&1\\Nov.&&4\\Dec&&6\end{array}\right]$

Hence , we have to put 6 in place of sept. month

✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴✴

$\leq step:- 4\geq$

• Well , we have one formula to find the day
• The formula of calculating Day as Below :-

===> $\frac{Date+Month+Century+year+Leap year }{7}$

===> $\frac{18+6+6+05+0}{7}$

===> $\frac{35}{7}$

===> 0 = Remainder

The 0 Day of the week was Sunday

✔✔ Hence ,  On 18 Sept. 2005 the day was Sunday   ✔✔
