This user earned the {{{year}}} Geohashing Day achievement

by celebrating in the ({{{latitude}}}, {{{longitude}}}) graticule on [[{{{coorddate}}} {{{latitude}}} {{{longitude}}}| May 21st {{{year}}}]].

If you celebrate this occasion on either Geohashing Day or the following Saturday you may display this ribbon on your user page. Yes, you may display both versions of the ribbon if you celebrate on both Geohashing Day and Mouse Over Day.

The Algorithm

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

The Algorithm that defines the sport of geohashing was first published on 21 May 2008. The anniversary of that date is therefore a special date for geohashers and deserving of special observances.

Date of Celebration

The official Geohashing Day is May 21st of each year, but for those who cannot geohash on weekdays, the following Saturday is designated Geohashing Day (observed), also known as Mouse Over Day. Both are appropriate days for celebrating.

Danatar and his hashcot celebrating Mouseover Day 2010

Celebrating Geohashing Day

The best way to celebrate Geohashing Day is to geohash. On this date, make a special effort to have a unique adventure and to invite new people to join geohashing. Get out there and do something you wouldn't normally do. It doesn't matter if you make the coordinates, as long as you have an adventure!

Sample celebrations

After the first Geohashing Day has passed, you will be able to browse the Category:Geohashing Day achievement to see a list of expeditions claiming this achievement. Perhaps some of the more noteworthy will be linked here.

Retrohashing

It is strongly preferred that you attempt to visit the coordinates generated for the actual date of your expedition. The current day's coordinates are always the first choice. There may be a geohasher in your graticule who does not use the wiki or peeron so has no way of knowing that you are going to an alternate location.

But, acknowledging that many graticules do not have even marginally accessible coordinates every day, and in order to expand the possibilities for adventure, Geohashing Day and Geohashing Day (observed) celebrations can include a retro hash to the coordinates for May 21st of any year since the announcement of the algorithm. Another possibility is to do both the actual geohash and one or more retrohashes. Perhaps you can find one near enough the days' coordinates to make that feasible.

Remember that for most awards other than the Geohashing Day ribbon you must reach the coordinates for that day. For example, you cannot claim Virgin Graticule, Consecutive geohash, Golf Geohash, Admit One Geohash or any other lucky location achievement if you are retrohashing.

Warning to those east of the Americas: - May 21st 2008 and earlier was before the 30W changeover.

Cake

Rhonda made this cake for Geohashing Day 2009

Cake is also highly recommended, especially if you succeed in transporting it to the geohash intact. Sharing cake with strangers at the geohash is a good way to tell people about geohashing. People willing to accept cake from strangers in party hats are probably the sort of people who would consider geohashing.

Mouse Over Day will occasionally fall on the 25th of May, Towel Day. This happens when Geohashing Day falls on a Tuesday, on average every seven years. The next occurrence will be in 2030.

Note: The anti-node of 21 May (141st day of the year) is 20 November (324th day of the year, being 141+183.5 rounded up or 184 in a Leap Year).

I simply named it Geohashing Day, but I also like Algorithm Day. I'd opt for celebrating it on May 21st, not on Saturday. If we make an achievement ribbon for this, the next Saturday might qualify for a honorable mention. Besides, another day coming up to celebrate, is Towel Day (May 25th). Someone should make a ribbon for knowing where your towel is while Geohashing. [[User:Koepfel|Koepfel]] <sub><small><small>[[User_talk:Koepfel|talk]]</small></small></sub> 21:26, 14 April 2009 (UTC)

-::I would recommend the nearest Saturday (May 23rd), because the original intention of the comic was that "Game Day is Saturday," and many people can't geohash on weekdays. -[[User:Robyn|Robyn]] 21:37, 14 April 2009 (UTC)
-:::The intention of the comic was to visit certain coordinates on a certain day. The saturday meetup was just the mouse-over text ;) I do see the point of people being busy (I myself probably won't have the time on that day), but the anniversary is on May 21st. This is why I thought of a honorable mention, maybe also for retro-expeditions on Saturday.

-Maybe "Algorithm day" the 21st, and "Algorithm day (observed)" the next (or nearest?) Saturday, to mimic moveable statutory holidays, with either counting as attending the anniversary celebrations? -- [[User:Rhonda|Rhonda]] 03:35, 15 April 2009 (UTC)
-I was already planning on creating a "Geohashiversary" achievement for making an expedition on the 21st. I like the idea of getting the achievement by just making an effort, because that's the spirit of geohashing: getting out there and doing something you wouldn't normally do, '''it doesn't matter if you make the coordinates as long as you have an adventure!''' [[User:Thepiguy|Thepiguy]] 05:00, 15 April 2009 (UTC)
-:I agree with adventure trumping just reaching the coordinates, but you should have to do something, perhaps tell three non-geohashers about it, perhaps`something zanier. -[[User:Robyn|Robyn]] 05:12, 15 April 2009 (UTC)
-::Bear and I like the idea of a "Algorithm day" on the 21st, and "Algorithm day observed" (or an honorable mention-type) on the Saturday.  We are also drooling over both suggestions here - '''attempting a unique adventure''' and trying to '''involve non-geohashers'''.  Perhaps a special ribbon? :-) -- [[User:Ncbears|NCBears]] 16:21, 15 April 2009 (UTC)
-:::I don't think we should add any other requirements. Dragging people along  is always a win, so there's no need to specificially do it on this day. For the honorable mention, chould it also be acceptable to retro-hash to the 21st's coordinates on the next Saturday or should they use Saturday's coordinates?

-Oh, I'm liking this, that's the hook for Algorithm Day: you can geohash the May 21st 2009 coordinates on May 21st, the May 21st 2009 coordinates on the Saturday, or the the May 21st ''2008'' coordinates on ''either'' May 21st ''or'' the Saturday. Also, why are there only four people involved in this discussion. Is the Main Page announcement box not as visible as I hoped? -[[User:Robyn|Robyn]] 22:07, 15 April 2009 (UTC)

Another possibility is to do both the actual geohash ''and'' one or more retrohashes. Perhaps you can find one near enough the days' coordinates to make that feasible.
-For graticules that have a land location, a retrohash of [[2008-05-21]] is being considered. Warning to all - this was before the [[30W Time Zone Rule|30W]] changeover. --[[User:Thomcat|Thomcat]] 15:19, 21 April 2009 (UTC)

-:I really like the idea of a [[2008-05-21]] retrohash, '''either on the 21st or the following Saturday'''.  it would be fun to go back to the saem point and possibly find a marker someone left from the year before.  Also in keeping with tradition, I'm notfixing spelling errors :-P -- [[User:Jevanyn|Jevanyn]] 19:03, 16 April 2009 (UTC)

-:::I am '''against the retrohash''' idea on its own, as my graticule, [[Palm Beach, Florida]], has an inaccessible hashpoint for that day.  Also, while it is great to relive a good moment from the past, the entire point of geohashing was to go out and do something new, '''go somewhere new'''.  One possible idea, which I would support, is to meet up at (or as close as possible to) the retrohash, and do a mass-migration to the new point for the day.  Sort of a reliving the past, but also moving towards the future kind of thing.  *shrug*  --[[User:Aperfectring|aperfectring]] 22:59, 16 April 2009 (UTC)
