The year is not shown and so we are often confused as to whether the card was created recently or a long time ago. We run into this when we periodically review/purge old cards so it is quite a visible Favro shortcoming that the team sees.
I suggest the general rule in the UI should be, "If you are showing a date, ALWAYS show the year as well". Even if the date is from the current year. It is important for readability that date formats are consistent.
