Is there any direct way to know the day on a specific date?
For example, take any date say 23-08-1980. Now, I want to know the day on this date (It could be any starting from Monday to Sunday).
Is there any formula or any other way to calculate this statistically?
Do not use any programming language.
Have a look at this Wikipedia page, http://en.wikipedia.org/wiki/Calculating_the_day_of_the_week#A_tabular_method_to_calculate_the_day_of_the_week
It goes over leap years as well.
