Welcome to the Geohashing Wiki. Geohashing was brought to you by the xkcd webcomic. Read this information in Deutsch - Español - Français - Svenska - and maybe other languages.

“	Hi, mom! - Are you at home? - No. - Where are you? - Um, near Garmisch... - Are you geohashing again? - Um, yes... - How many of you are there? - Nine... - Well, have fun, but don't tell your father. Bye.		”

What is this?

The Algorithm as shown in xkcd comic #426, published on 21 May 2008.

Geohashing is an adventure, comprising journeys to random places within a given area. Every day, effectively random locations are generated by an algorithm that achieves randomness using stock market data. It is a Spontaneous Adventure Generator. A set of coordinates is generated for each 1°×1° latitude/longitude zone (known as a graticule) in the world. The coordinates can lie anywhere in the graticule — 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.

The generated coordinates are used as destinations for adventures, à la Geocaching, or for local meetups. After the fun, please 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.

Official xkcd meetups

Rhonda, Robyn and Wade at the 25 April 2009 coordinates for Vancouver, BC, Canada

Official xkcd meetups happen every Saturday afternoon at 4:00 p.m.(*) at that day’s normal geohash coordinates. It is considered a Saturday meetup if you are there at 4:00 p.m. or if you meet people, but you are most likely to encounter other readers of xkcd if you go at the designated time. Bring games!

You're encouraged to geohash on any day of the week that the coordinates are accessible to you, but if you attempt one meetup all week, make a little extra effort to have it be on Saturday. All meetups start at 4:00 p.m. or as designated on the graticule page.

There's even an achievement for making it to 100 Saturday meetups.

*In some areas, 4:00pm is too close to sunset during the winter, so earlier meetups are often more appropriate. See individual graticule pages for local conventions.

Recent and Upcoming Coordinates

The coordinates for the next Saturday meetups, scheduled for 5 April 2014, will be based on the Dow’s opening price published at 09:30 EDT (13:30 UTC) on Friday 4 April. See timeanddate.com to convert this time to your local time zone.

• Coordinates: Thu 3 Apr* | Wed 2 Apr | Tue 1 Apr | Mon 31 Mar | Sun 30 Mar | Sat 29 Mar | Fri 28 Mar | Thu 27 Mar

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.

Gallery of Recent Expeditions

The gallery for each day is added to this page automatically, but pictures are selected to the gallery by us. Any geohasher is welcome to add a picture from that day. Just add your image name in the list at the “add yours” link. If the gallery hasn't been started yet, copy the format from the previous day, or read the how-to. Please also write an account of your expedition, even if only a short one, so that people can click the link on your picture and find out more.

This section documents hash expeditions that geohashers wish they could make, but have not been able to for the reasons stated.

2014

• 2014-02-18 52 4 THE place to waste your time [1] On the dock of the bay no less. But, the restricted part of the naval base. JwB (talk)09:52, 18 February 2014 (CET)
• 2014-01-30 Global Hash [2] 28N 126E South China Sea, north-west of Okinawa. I have a friend sailing through this area at the moment, about 240km South East so perhaps two days sail from this GH. However, there is no chance of 'diverting' him today. Hence, no chance of various achievements (he is capable of navigating by compass AND sextant, has a cat onboard the yacht to pat, etc.) A pity! 1PE (Canberra) (talk) 17:30, 29 January 2014 (EST)
• 2014-01-11 -34 149 [3] ON the south-bound track of a bendy bit of the Melbourne, Australia to Sydney, Australia main train line, near Gunning, New South Wales (west of / in the graticule of Goulburn, Australia) -- SOMEONE must be on a train! 1PE (Canberra) (talk) 18:09, 10 January 2014 (EST)

2013

• 2013-12-03 39 -84 Cincinnati, OH. Smack on the tarmac of Lunken Airport. Almost epic enough to justify the police record. Humbucker (talk) 14:15, 3 December 2013 (EST)
• 2013-11-27 global globalhash, Mongolia is about 1km off a dirt road around 10km north of Tosontsengel, Mongolia and it has an airport.1PE (Canberra) (talk)
• 2013-10-25 global GlobalHash in Spain, 48 km from Ponferrada, 113 km from León, 210 km from Salamanca, 366 km from Madrid --LeslieHapablap (talk) 09:57, 24 October 2013 (EDT)
• 2013-07-12 41 -6 (GlobalHash) by 1PE - northern Portugal, just off the N220 east of the village of Carvalhal, itself east of Torre de Moncorvo. Even do-able from Spain: Salamanca or Zamora.
• 2013-07-04 34 35 by 1PE - Syria! Near a major road intersection, in an olive grove.
• 2013-03-28_39_-76 by OfficeLinebacker - In some woods near a river near Conowingo, MD. Already went to two today, don't feel like driving another 4 hours. Looks nice and very reachable, though.
• 2013-03-20 33 72 (GlobalHash) by 1PE - Western side of the Indus River valley, about 25km south of Nowshera, Pakistan; only 60km from Pashawar.
• 2013-03-15 -34 149 by 1PE - very near an interesting Google Maps feature, an aircraft pictured in flight but I couldn't justify going 70km each way to the hash.
