HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

In my opinion, it would be better to have the date first. This way, the saves would be sorted chronologically.
Essentially, the only inconvenience with the current saves is that the month is written out in letters instead of numbers, which causes them to be out of order.

By the way, I think it would be perfectly acceptable to write the year with two digits instead of four. I.e., YY.MM.DD.
