time.clock() should be time.time() -- otherwise you are measuring CPU time instead of wall clock time, at least on Unix platforms. and ActiveTcl® are registered trademarks of ActiveState. Otherwise known as the "perpetual calendar" problem, it's a method for mentally calculating what day of the week any given date fell on. However, what I can immediately see is egregiously wrong is the implementation of the Doomsday Algorithm (used to get the day of the week given the day, month, and year). clock versus time. It takes advantage of each year having a certain day of the week upon which certain easy-to-remember dates, called the doomsdays, fall; for example, the last day of February, 4/4, 6/6, 8/8, 10/10, and 12/12 all occur on the same day of the week in any year. i.e. Algorithms are derived from the calculations of John Conway, Lewis Carroll and many other mathematicians in history who worked on the calculation of Dooms Day.To calculate Doom’s Day of a particular year following algorithm is used:-, Here [ ] is Greatest Integer Function.Anchor day changes after 100 years and repeats after every 400 years in the following way –. He realized that certain dates in every year all share the same week day. The point is to make the student look for the algorithm's that allow you to do this and then implement one of those as a python script. share | improve this question | follow | edited May 17 '16 at 14:28.

Explanation Jan 1st 1 AD is a Monday in Gregorian calendar. This is a good tool for adding to your use of worthless information. We can then convert this matrix to a graph. code. In any given year, there are certain easy-to-remember 'special' dates that all happen to occur on the same day of the week. While I implemented a relatively naïve approach to maximum matching, we can implement much better solutions. I highly recommend reading the article by S.W.

The Doomsday Algorithm is a method developed by John Conway to find the day of the week of any given date based on a perpetual calendar. Doomsday for the current year in the Gregorian calendar (2015) is Saturday.

Finding out which guards to match now becomes a maximum matching problem. It is simple enough that, with practice, it can be done mentally without paper or pencil. DOOMSDAY, a Python library which is given the year, month and day of a date, and uses John Conway's doomsday algorithm to determine the corresponding day of the week.
