Your question is nice and I really glad to answer such type of questions

As you know 1980 is a leap year

And you glad to know in 1600 calendar is described !
As we Indian are extraordinary persons have a great knowledge of maths we formed the formula for finding day of any of the year. But it has some limitations too it is only able to find till 20th Century

So we made certain code for month to finding that

January = 1
Feb= 4
March =4
April =0
May =2
June =5
July = 0
August =3
September =6
October =1
November =4
December =6

And according to question 18th century is given so for 18th century we found a code that is 18th century = 2

©--------------------©

So, Let us finish our discussion and begin with a formula to find the day of 25 December 1980

Day = Date +Month + century + year +leap year
________________________________

7

=> 25+ 6+2+ 0+ 4
______________
7

=> 37
___
7

=> 5.28

5 now we have to subtract 1 from it

4 is the answer

As we know 4th day of the week is Thursday hence the day on 25December 1980 is Thursday
