Note: The graticule map appears to be buggy for location -180, and the google maps data is also incomplete
Taveuni is the third largest island of Fiji in the Pacific, and is one of the few places where the 180th meridian crosses land. However, unlike the prime meridian, the neighbouring geohashes are NOT mirrored around the line. Rather, geohash algorithm meridians are at 30W and 180. ie, you use the different 30W formula adjustment on each side of the line - allowing for neighbouring hashpoints to potentially be VERY close. (someone else can work out the odds for two graticule points to land on Taveuni for the same day)
A good example of this is the 12th May 2008, as shown below...
