|style="color:#000;"| Welcome to the '''Geohashing Community Wiki'''.  [[Geohashing]] is a ''Spontaneous Adventure Generator'', brought to you by the [[xkcd]] webcomic.

[[Image:Coordinates.png|right|240 px|[[The Algorithm]], as shown in [[xkcd]] [http://www.xkcd.com/426/ comic #426].]]
 
[[xkcd]] [http://www.xkcd.com/426/ comic #426], published on 21 May 2008, contains an [[algorithm]] that generates random coordinates around the world every day.  Everyone in a given [[Graticule|region]] gets the same set of coordinates.  As such, these coordinates can be used as destinations for adventures, ''à la'' [http://en.wikipedia.org/wiki/Geocaching Geocaching], or for local meetups.

|style="color:#000;"| '''Play with the coordinate calculator at [http://xkcd.com/geohashing http://xkcd.com/geohashing].'''  All coordinates refer to the [[wikipedia:WGS84|WGS84]] datum.
 
 
 
Every day, the [[algorithm]] generates a new set of coordinates for each 1°×1° latitude/longitude zone (known as a [[graticule]]) in the world.  They are randomly placed -- they could be in the forest, in a city, on a mountain, or even in the middle of a lake!  You can use this wiki to document the daily coordinates (geohashes) you've been to.
 
 
 
Unless you can accurately predict the [[DJIA|stock market]] down to the penny, you can't figure out what the coordinates will be ahead of time.  You can first calculate a weekday's coordinates at about 09:30 [[Eastern Time|US Eastern Time]], and on Friday you can calculate the coordinates for each day that weekend.
 
 
 
When visiting geohash locations, please [[geotrashing|respect the area]] you are visiting.  Absolutely do not litter or otherwise disturb the natural integrity of the area.  However, if possible, creating some kind of a marker out of nearby materials (i.e. cairn of stones, blair-witch-style 'stick figures', etc.) is encouraged.

Welcome

Welcome to the Geohashing Community Wiki. Geohashing is a method for finding an effectively random location nearby and visiting it, i.e. a Spontaneous Adventure Generator. Geohashing was brought to you by the xkcd webcomic.
The Algorithm, as shown in xkcd comic #426.

Every day, the algorithm generates a new set of coordinates for each 1°×1° latitude/longitude zone (known as a graticule) in the world. The coordinates can be anywhere -- in the forest, in a city, on a mountain, or even in the middle of a lake! Everyone in a given region gets the same set of coordinates relative to their graticule.

As such, these coordinates can be used as destinations for adventures, à la Geocaching, or for local meetups. After the fun, why not document your expedition? The rest of us would love to read your story, see your photos, and cheer your success (or commiserate with your failure). You can use this wiki to document the daily coordinates (geohashes) you’ve been to or tried to reach.

Disclaimer: When any coordinates generated by the Geohashing algorithm fall within a dangerous area, are inaccessible, or would require illegal trespass, DO NOT attempt to reach them. Please research each potential location before attempting to access it. You are expected to use proper judgment in all cases and are solely responsible for your own actions. See more guidelines.

Official xkcd meetups

Felix Dance, Mdixon4, Rhonda, Lachie and Stevage meet up at the 28 December 2015 (a Monday) coordinates for Bairnsdale, VIC, Australia.

Based on the title text from the comic that established geohashing, the "official" meetup day was interpreted as being Saturday; that is, the day one would have the best chance of meeting others -- see also Mouseover Day. Additionally it was decided through convention that a good meeting time would be 16:00 local time (4:00 P.M.)¹

However, neither of these are hard rules, and they were formulated at a very different early stage in the sport's history. Nowadays and for quite awhile actually, any date or time can be good (or bad, depending on how many other hashers are near you) for meeting up, especially if prearranged. Note that this only applies to that day’s normal local geohash or globalhash coordinates, if you try to go to an alternate location without telling anyone else, it's highly unlikely you'd meet up with a hasher there (obviously).

¹Or earlier if that would be too close to sunset during the winter, or other quirks of temporal tradition; see your local graticule page for consensus there.
