The Adventure Starts Here

Geohashing is a game of spontaneous adventure generation played around the world since 2008. You will explore random locations, meet fellow geohashers, brave the elements, unlock achievements, and then come back here to document your expedition.

How does Geohashing work?

Every day, effectively random locations are generated by an algorithm that derives randomness from stock market data. A set of coordinates is generated for every 1°×1° latitude/longitude zone in the world, or graticule. The coordinates might be in a field, a forest, a city, up a mountain, or out at sea! Everyone in a quadrant of the globe 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)! Join the other 'spot spotters', be out standing in your field and use this wiki to document the daily coordinates (geohashes) you’ve been to or tried to reach.

The daily coordinates are repeated for each degree all round the planet, but there is also a single globalhash, rare, valued and much harder to reach.

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.

Recent and Upcoming Coordinates

The coordinates for the next Saturday meetups, scheduled for 23 November 2024, will be based on the Dow’s opening price published at 09:30 EST (14:30 UTC) on Friday 22 November. See timeanddate.com to convert this time to your local time zone.

Coordinates: Thu 21 Nov* | Wed 20 Nov | Tue 19 Nov | Mon 18 Nov | Sun 17 Nov | Sat 16 Nov | Fri 15 Nov | Thu 14 Nov
* Only known for regions east of 30W longitude. Coordinates for regions to the west announced 14:30 UTC, 21 November.

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.
