I guess that the season change will be the 18th day of this january and that the first league match will be the 28th day of this january.
It would be kind from the Admin make an official advertisement with the date of the new season and the very first official match of the new season.
I think it is a matter of fairness to those who support the game to make announcements like this even if the dynamics of season breaks are clear enough for those who are more attentive and made comparisons with the breaks of past seasons.
