I would like a checker the same as GC4T8MP, to place in Ireland.
The idea is that days are counted between when a cacher logs a cache online, and the difference in days is calculated between their "found" log, and the previous online "found" log. these days are then added up for all caches to total 36,525 days. (the total number of days in a century, including leap days)
All caches, archived, and active, of all types count towards the numbers.
