Answer(s):

Example: Find day Name of 11 September, 2019.

11 Sep, 2019

= 11 + 5 + (2019 - 2000) + 3 

[here, (2019 - 2000) modulus 4  == 3] [4 is for formula]

[Modulus mean remainder] [and always subtract the century year]

= 16 + 19 + 3

= 38

Now, 38 modulus 7 == 3 [here, 7 is for formula]

From the formula, (Formula given is given below)

3 mean Wednesday

So, 11 Sep, 2019 is Wednesday.
