What is this?
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). 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
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 27 April 2024, will be based on the Dow’s opening price published at 09:30 EDT (13:30 UTC) on Friday 26 April. See timeanddate.com to convert this time to your local time zone.
- Coordinates: Thu 25 Apr* | Wed 24 Apr | Tue 23 Apr | Mon 22 Apr | Sun 21 Apr | Sat 20 Apr | Fri 19 Apr | Thu 18 Apr

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.
