Hi @anon88498403, thanks for reaching out and providing your feedback on this feature. As @Bryan_TeamKickstart and @lpb mentioned, as it stands, this feature is currently not available.
We closely monitor customer feedback and share it with our product team and we currently have an existing request in the Forum where you can upvote and we will keep the thread updated if we have plans to implement this in the future. Add three-character day of week to date tooltips at least, and some date references too
Please note Forum Leaders, Partners and Ambassadors are always keen to support Asana users in the Forum with tips, use cases and workarounds to try to help everyone unblock specific workflows 
Let me know if you have any other questions! Have a nice day!
