Simple hashtag proposal for dates: datetags for the #indieweb
In summary by example:
* #2026_08_04 ISO8601 YYYY_MM_DD date of this post
* #2026_216 ISO8601 YYYY_DDD ordinal date of this post
* #2026_08 ISO8601 YYYY_MM month of this post
Many of us posting on the indieweb often post about things in the past. Photos, events, or sometimes throwback posts. Hashtags communicate and aggregate what posts are about. Posts about the past are usually about a specific date in the past, or sometimes an entire month. Thus it makes sense to use hashtags for those dates and months.
I have been hashtagging such posts about the past for several years, and with some iteration have developed a convention that works for international readability, and is linked and indexed in #federated #hashtag systems like #ActivityPub (#Mastodon etc.).
Examples of posts 10 years ago and this past week that use datetags:
* https://tantek.com/2016/153/t4/june — monthtag and datetag
* https://tantek.com/2026/215/t1/watched-odyssey-metreon-70mm-imax — normal and ordinal ISO8601 dates.
Additional possibilities to explore:
* yeartags — hashtags for entire years
* timetags — hashtags for specific times, undated/floating times
After several web searches I didn’t find any prior proposals for hashtags for dates or times. Hopefully by hashtagging this post, future web searches will find this proposal.
Have you hashtagged your posts with dates or times? Share your examples!

Nice #IndieWebCamp discussion session with Kevin Marks (@kevinmarks@indieweb.social @kevinmarks@xoxo.zone @kevinmarks) on the topic of auto-linking¹.
I’ve implemented an auto_link function² that handles quite a few use-cases of URLs (with or without http: or https:), @-name @-domain @-domain/path @-@-handles, hashtags(#), and footnotes(^).
Much of it is based on what I’ve seen work (or implemented) on sites and software, and some of it is based on logically extending how people are using text punctuation across various services.
It may be time for me to write-up an auto-link specification based on the algorithms I’ve come up with, implemented, and am using live on my site. All the algorithms work fully offline (none of them require querying a site for more info, whether well-known or otherwise), so they can be used in offline-first authoring/writing clients.
I have identified three logical chunks of auto-linking functionality, each of which has different constraints and potential needs for local to the linking context information (like hashtags need a default tagspace). Each would be a good section for a new specification. Each is used by this very post.
* URLs, @-s, and @-@-s
* # hashtags
* ^ footnotes

I recently wrote a high level summary blog post:
W3C Technical Plenary and Advisory Committee (TPAC) Meetings 2023
https://tantek.com/2023/262/b1/w3c-technical-plenary-tpac
of my time at the #W3C (@W3.org, @w3c@w3c.social, @W3C) #TPAC the week before.
Posting this note to explicitly #hashtag that article with topics mentioned therein:
#Sevilla #Seville #Spain #WICG #SocialCG #SWICG #Fediverse #SocialWeb #sustainability #IndieWeb #ActivityPub
because I forgot to put explicit categories (p-category markup) in the article post.
Adding that markup after publishing, and then sending an ActivityPub update (via #BridgyFed) is apparently not enough for #Mastodon to notice that the Update has new tags to display and aggregate on tag pages. In my next #w3cTPAC article post I’ll be sure to include category markup before publishing and see if that works.

@dwmatiz Also I could expand on what I meant: Only programmers would have anything against the specific '!' character as opposed to others, as that's the only area (I know) it has semantic meaning when prepended to a word. ¡Not even Spain uses it!
And if there's no specific preference against for most people, then reasonably there's no reason to choose one character over the other. By following the rationale of how the #hashtag was chosen by normal people because noone ever uses # at all, but we're sort of out of characters normies don't use _and_ can be written on a majority of keyboards easily (~ is not easily written, to tie back into that suggestion).

@vinzv on the other hand !gnusocial doesn't have centralised hashtags, i.e. clicking #hashtag will only show posts of the poster's instance

@eleanor70001 Most software turns a #Hashtag into a link, just click or tap or select and follow it
