I was thinking about publishing but wanted to know the time frame for different conferences. So I spent a hour and compiled a list at Google Calendars. All the big names are on there, such as Infocom, Sigcomm, ACM Multimedia, CoNext, etc
Or the full page HTML link, iCal link, and XML link.
I’m hoping that this will be of use to others, and that I will receive feedback on conference that I’ve missed.
