is there a way to figure out the day of the week of a particular date?

Question

for example : if August 6, 1987 is a thursday then how do you figure out what day of the week it is without looking it up? is there a calculation or any kind of formula?

Answer 1

I wrote an article for Wikipedia that shows you how. It is at http://en.wikipedia.org/wiki/Perpetual_calendars#Perpetual_calendar_formula

Answer 2

Yes. Google Gauss's formula. Automatic watches are programmed with it, so if the watch has been lying in a warehouse for 2 years without a battery, as soon as you power it up and set the date, it automatically displays the correct day of the week. If you think about it, there are only 14 different possible calendars; 7 for ordinary years, depending on which day January 1 fell on, and another 7 for leap years.

Answer 3

I don't believe there is an easy to remember formula. That is what makes an idiot savant so amazing. I have seen one on TV that can do what you are asking, but a formula for it was never revealed.

The Gregorian Calendar is a repetetive calendar system that allows you to create a pereptual calendar with a particular day matching up to a date every certain number of years.

The short answer to your question would have to be that there probably is, but good luck learning it well enough to be able to apply it.

Answer 4

Here's a web site from the University of Texas which approaches the question from various directions. I've tucked a Wikipedia site in, too, because it addresses algorithms. Hope it helps - it was a good question.
