GitHub is where people build software. Doomsday for the current year in the Gregorian calendar (2015) is Saturday. A note about the implementation: It's not necessary to implement the algorithm explicitly in a practising program since Python's standard library already knows how to compute the weekday given a date. Overview. Take the floor of the above value and then add. Here is a roughly equivalent program that uses batteries already included in Python: (I chose to print ISO 8601-style dates -- american-style dates are confusing to me. generate link and share the link here. There are many algorithms written to calculate which day of a week in a year has the highest possibility of doomsday falling on that day.All the statements are with respect to Gregorian Calendar. The Java version was done first, and then Python one follows the same algorithm, just with the Python syntax. The Overflow Blog Open source has a funding problem.

This is a Python progam that lets you practice determining the day of week for any date. The main difference is in the data structure used to hold the final list. You could customize the date range, but that creates the need for added coding, and this range is sufficient once you figure out that 2400 has the same doomsday as 2000, and 2500 the same as 2100, etc. A simple command line utility implemented in Python for practicing mental calculation of the day of the week for dates in the Gregorian calendar, using the Doomsday rule algorithm originally described by John Horton Conway [1]. | Contact Us source and ActiveTcl® are registered trademarks of ActiveState.
