xkcd centurion achievement

This user earned the xkcd Centurion achievement

by attending {{{count}}} Saturday meetups.

Anyone who attends 100 XKCD Saturday meetups has achieved the XKCD Centurion. Several intermediate steps are available for those who want to document their progress.

A Saturday meetup has been achieved for a geohasher, when on meet-up day:

The geohasher is present at the official coordinates for that date, at the official meet-up time. That time is Saturday 4 p.m. unless otherwise established for that graticule by permanent or long standing agreement. Some graticules have shifted the meet-up time to Sundays, or to an earlier time of the day to meet in daylight. This is permitted.

or

The geohasher meets other geohashers who are trying to reach the official coordinates, and are travelling independently, whether or not anyone succeeds.

or

The geohasher meets other geohashers at a prearranged alternate Saturday meeting location., whether or not they succeed.

That is, you either have to be in the right place at the right time, or you have to actually meet someone. It's not a Saturday meetup if you dash by at a random time. The purpose of this award is to encourage actual meetups with other geohashers. These criteria are intended to support that while not eliminating opportunities for active geohashers in difficult, unlucky, or unpopulated graticules.

Note: Unless someone would go for some Time-Traveller Geohashes along the way (or hash a lot in graticules which have changed their official Saturday meetup time), it would have been impossible to earn this achievement until the 100th Saturday since the Algorithm was published, 17 April 2010. However, nobody even came close to 100 at that date.
