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.
