I was in desperate need for an DDate equivalent running on Windows. DDate is an unix implementaion of date accoridng to the erisian calendar described in the principia discordia.
I only found some C Implementations. And since it’s fun to do I ported the original Discordian Date C code to C#.
You can download the C# sourcecode, licensed under CC-BY-NC here.
I also created a web page which displays the current discordian date and offers you to convert any gregorian date into discordian date representation.
This page can be accesses here. You can call another page with parameters and you only will get the ddate output back:
