You can try Mayday right now without any installation!

The only requirement is a Sun Java 6 Webstart Environment. If you want to use the Mayday-R interface, a local installation of R is, of course, required.

We offer two versions:

• Mayday stable webstart (Release 2.13)
  … or run it with 2 GB memory*
  … or run it with 6 GB memory* (only 64 bit Java!)
  – Recommended version
  
  
• Mayday experimental webstart (development version)
  … or run it with 2 GB memory*
  … or run it with 6 GB memory* (only 64 bit Java!)
  The experimental version contains new features and improvements, but not all functions have been tested as thoroughly as in the stable version.
  

*) On some machines, you will have to start Mayday twice to get the correct amount of memory. Mayday displays available memory in the bottom left status bar.

If you use Mayday for your scientific work,
please use the correct citation.
