An index of months and years by the serial number of the article?

Question

Habr

Posts and questions on Habré have serial numbering. It would be quite logical if, by the number of the article, one could see the month and year of its writing without opening the link itself, in the title. For this, it is enough to store fifty dates on the page, which takes up very little space - 70 numbers for 6 years of Habr and 3 times less for QA.
I would like to ask a specialist working on Habré to bring this list of numbers by making one request to the database (the number of the first article published in each month) in order to create this list for the userscript.
The same can be done for comments to immediately see how old the link was brought somewhere in the text.
But what if this is done officially, as a function of the site? You can load with Ajax by first holding the mouse over the link.

Answer 1

UPD : around September 5, these hints were implemented in the HabrAjax userscript , the last year - by months, the previous ones - by years (still little data).
