Created by Vivek

Solve Later

Today's day and date will be given to you. By utilising that you need to find the day of the old date. (Date will be in DD/MM/YYYY format, Consider leap years also).
Example:
TodayDate='20/11/2013'
Today='Monday'
UnknownDay_Date ='19/11/2013'
So here you need to provide output as UnknownDay='Sunday'
Solve the problem in the hypothetical world where 16 April 2019 happens on Saturday instead of Tuesday.
Note: It is not like using "datestr" and finding result. You need to calculate the number of inbetween days and then find the answer.

Its not like using datestr and solving this. You need to calculate the days and divide it by 7, take the reminder and increment that many days to present day.

Problem statement would be much better with an additional sentence:
"Solve the problem in the hypothetical world where 16 April 2019 happens on Saturday instead of Tuesday."
Otherwise this is just lame.
