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