Every day, the algorithm generates a new set of coordinates for every region. They are randomly placed -- they could be in the forest, in a city, or on a mountain.  You can use this wiki to document the coordinates (geohashes) you've been to.

== How does Geohashing work? ==
 +
Everyday, an [[algorithm]] generates a random coordinate from stock market data. That coordinate can be applied to every 1°×1° latitude/longitude ''[[graticule]]'' in the world, giving a point that might be in a field, a forest, a city, or even [[Water Geohash|out at sea]]! Everyone in the world gets the same set of coordinates relative to their graticule.

Unless you can predict the stock market, you can't figure out what the coordinates will be ahead of time.  You can first calculate a weekday's coordinates at about 9:30 AM, and on Friday morning you can calculate the coordinates for each day that weekend.

Each day, people try to get their nearest generated coordinate, for an adventure, to discover somewhere new, or to meet up with other geohashers. Afterwards, you can '''[[expedition|document your expedition]]'''. The rest of us would love to read your story, see your photos, and cheer your success (or commiserate with your [[Achievements#Consolation_Prizes | failure]])!

The Adventure Starts Here

Geohashing is a global game of spontaneous adventure generation with over 17,000 expeditions since 2008. You will explore random locations, meet fellow geohashers, brave the elements, unlock achievements, and then come back here to document your expedition.

It ultimately took me almost two hours to travel the 1.4 km and to reach the hashpoint. Sometimes I got more stable ground under my feet, sometimes –– I sank to metre-deep snow and could barely climb up. But I consider Mother Nature my bitch and would let nothing stop me.

The Algorithm was invented for xkcd comic #426, published on 21 May 2008.

How to play?

  1. Get today's coordinates with a coordinate calculator
  2. Go there (or as close as you safely and legally can)
  3. Create an account (Returning after a break? All accounts created before 2020-02-02 were deleted; you'll need to sign up again)
  4. Write about your expedition!

How does Geohashing work?

Everyday, an algorithm generates a random coordinate from stock market data. That coordinate can be applied to every 1°×1° latitude/longitude graticule in the world, giving a point that might be in a field, a forest, a city, or even out at sea! Everyone in the world gets the same set of coordinates relative to their graticule.

Each day, people try to get their nearest generated coordinate, for an adventure, to discover somewhere new, or to meet up with other geohashers. Afterwards, you can 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.

Each day there is also a single globalhash somewhere on Earth: 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.

Gallery of recent expeditions

Every expedition should have one photo in that day's gallery, selected manually. Please add yours with the "add" link. If that day's gallery hasn't been started yet, please start it.

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.

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.
