Experience design calendar, featuring conferences and workshops worldwide, is now hosted on Eventful (and no longer on Upcoming.org) because Eventful provides so much more functionality and is also much more user friendly.
Also on Eventful are experience design groups for Asia, Europe and North America, which only contain events of global relevance and those in your region.
